God I love you. I just recently started messing with OCR's, specifically Tesseract, and I was reading through some documentation on the steps and after a few hours just wanted to end my life hahahaha. Thank you for this, this is extremely encouraging. I can't wait to try this!
Tesseract's documentation is abysmal.
I tend to think about tesseract documentation as the Augean Stables
Haven't watched the video yet, but if this works, you'll have my eternal gratitude
Great tutorial. Using WSL I was constantly getting new errors. Switching to OS installed on VirtualBox solved it. I was able to train my dataset-it's surprisingly easy.
Could you help me with the directory structure. I am a bit confused on how it is made?
Estuve rompiendome la cabeza tratando de entender el tutorial oficial y tú lo explicas de una manera sencilla. Soy tu suscriptor numero 666, Muchas Gracias.
I think the reason why the word error rate is high is because the font doesn't distinguish uppercase with lower case (it's all upper case) but the ground truth label distinguish between the two.
If I have the line wise hand written image for any language with bounding box and the words so and so can I train it on this LSTM network ? will it work ? and could you share your thoughts on the backbone of LSTM architecture with the flow diagram says : how fonts is helping with training data
Thank you for making this video. But I can't wrap my head around where to put all those data files to? I'm trying to fine tune variations of letters with accents, and I'm helpless.
Thank you for doing this tutorial. Can I use the Text2Image approach to generate box files and tif files to train new font for Tesserat 4.0?
hi when u say we are using text2image nothing AI, but the text2image must be also some model only right ?
Hi Gabriel! Thank you so much for the video. A question I had was where did you upload your apex legends ttf file in the code directory like where should it be place? I have a custom font ttf file that I want to train on
did find any answers?
I want to train tesseract with an image file I have (consisting of several lines of text), but I'm not sure how to go about it, starting with creating the train data. I'd really appreciate your tips (URLs for reference, etc).
Hey Gabriel, I am following your steps to train on my model on hand writtent text. But it is always failing with this erro:
unicharset_extractor --output_unicharset "data/Apex/my.unicharset" --norm_mode 2 "data/Apex/all-gt"
Failed to read data from: data/Apex/all-gt
Wrote unicharset file data/Apex/my.unicharset
Can you please help me here? I am stuck. Thanks!
I've been experimenting with this tutorial for three days , the file structure and the GitHub doesn't necessarily match, can you please update the repo if possible . I am having too many folder inconsistencies when trying to to connect the dots here as it was brushed over really quickly , thank you :)
Is there any way to perform RTL languages/fonts fine tuning in windows just like this?
the title is for new font , can I take it as new language ? using TIFF
Thank you very much for this. One question. Can we train Tesseract with non unicode fonts using the same process?
I'm pretty sure, as long as text2image works correctly. If text2image doesn't work correctly you can either come up with another clever ways (like Python scripts) of automatically generating ground truth data (.gt.txt, .box and .tif files), or worst case, create them manually.
I want to custom train Tesseract 5 to read the license plates of the car which are detected using YOLO model. How can I do these as I have couple of thousand images? Help
What are the steps I need to follow?
I tried with this font for hindi language ( Kruti Dev 010 ) even tried with Kruti Dev 016 but its showing : Error: Call PrepareToWrite before WriteTesseractBoxFile!!
I have bunch of plate with some text on it , goal is change the image to text, special font is trained but not effective , how can i train tobetter result, thanks for help
Hi Gabriel (@AstuteJoe), thank you for the elaborate tutorial.
I have a doubt though, once i followed the tutorial, generated the tif, gt.txt and .box manually. My training quits with a zero error rate before the max iterations. But when i use the generated trainneddata file, it gives the error "Error: Tesseract (legacy) engine requested, but components are not present in /use/share/tesseract-ocr/5/tessdata/lang_name.traineddata!! Failed loading language 'lang_name' Tesseract couldn't load any languages! Could not initialize tesseract."
Can you please suggest what i missed?
I didn't understand how to run the training command after downloading the two folders from github. I have Windows system
.lstmf files are missing. please help me to where i am wrong.
Hi Gabriel. I came across Tesseract today. I'm curious will I be able to train it to learn an arabic font?. I have a bunch of pdfs which are written in an indigenous language. The idea here is to train it on some sample pages so that it will be able to read it. It includes diacritics so I'm not sure if it will work.
Check the comments, a bunch of people train it for this exact intent
can we train the tesseract without any font ? if not why cant we ?
Thanks for the tutorial Gabriel. I wanted to ask how could I do this process if I have the images in text? I guess I need to do the .txt file and the .box file and then just run the training command.
Do you know any software that I could use to create the .box file from the images I have?
Thanks in advance!
I have seen people use the jTessBoxEditor: vietocr.sourceforge.net/training.html
@@AstuteJoe one more question, how would you use the newly trained model in python?
Thank you
@@ivanmongebadilla9454 I think just a parameter lang='your_new_model_name' as long as the new model is in the tessdata folder
Is it necessary for the box_file to be for each character or is it okay for it to be one word per bounding box?
I tired with your font but didnt work its throwing like :: Could not find font named 'Arial Unicode MS Regular'.
Pango suggested font 'Liberation Mono'. tried with arial but didnt work
when tesseract training is start it show the bellow warning
Can't encode transcription: 'पिए वई। ज़ख़मनि जो सूर वधंदो वियो हू चीखन्दो for Sindhi
how I can handle this problem?
Thank you for making this video. It helps me a lot. But I have a problem that when I copy and replace link to save dir or language_code..training_text, it appears that all of those generated image are white blank images. Pls help me out of this :
Thank so much sir for ur clear explaination and code
Great Video !
I'm getting this error when i try do run the training command:
"Failed to read boxes from data/FE_Font-ground-truth/eng_16.tif"
The file eng_16.tif not seems to be empty and it's very similar to all other trainning files. Im running with MAX_ITERATIONS=100 and with i delete the file that seems to be the problem, tesseract would throw the same error but with a different file. Does anyone could please help me ?
Hi.I try this on colab. I install tesseract and go on to run split_training_text.py and get this error FileNotFoundError: [Errno 2] No such file or directory: 'text2image'. Is there a solution?
one last question to shoot up, basically the Tesseract is not trained with handwritten text I guess and its trained on line files of system text which again converted to images on line basis for training. ? is my assumption true ?
Hey, It seems like you were also looking to train tesseract with handwritten text. Did you do it? If so please shade light, I am so lost
@@dhirazz training is not an easy thing as you need huge amt of data and they as well clearly said training is not gonna make any sense ( google ) hence,if u wanna try adjusting the parameters then deep dive into cpp
Hi, I am having issues with the last make training command. It throws out a error "No module named 'PIL'".
I have the Pillow library install but the error is still there. I am trying to solve this issue for a long, long time.
If you know something I will appreciate the help. I wanted link to my github issue but I am afraid youtube doesn't allow link.
Hey, long time passed, But for others having the same issue, creating an virtual env and then installing requiremnets.txt (of the tesstrain repo) in it may fix the issue, at least for me it worked! also check if all txt files have related box files or not!
How do you get suggestions in your terminal for auto completion of commands.

So far, the only tutorial on Tesseract 5, the old model of training by bash has been abandoned since December 2022
So, are you saying this video is now not useful at all?
Brother you can train for urdu nashtiliq font there no accurate trained data on net please
Hey Gabriel, nice vid, I am actually using it to train tesseract on Aurbesh font/language from star wars look it up it would explain a lot, each letter has a corresponding English letter I have collected roughly 100,000 sentences using your program and trained it with the command you provided but when I run a 6 letter word it completely melts down and just outputs the incorrect answer, I have changed iteration to small and big but no luck, I am wondering if you can help me or point me in the right direction. Thanks a lot
Hey you collected font but whats the training text data is that of Aurbesh ?
Hi ! I don't know if you resolved your issue since 1 month but don't forget to set a huge MAX_ITERATIONS to the make training. I personally set it to 10000 and it was quite better, it might be really enough for you if you have 100000 sentences. If you want to know the result check the log while the model is training, for example :
At iteration 7800/7800/7800, Mean rms=5.642000%, delta=49.022000%, BCER train=97.817000%,
BWER train=100.000000%, skip ratio=0.000000%, New best BCER = 97.817000 wrote checkpoint.
BCER is the error rate for characters and BWER the error rate for words, you can see that at iteration 7800 it was higher than 95% and after the 9500th iteration I got several improvements.
when i run the training command, its gives me the bellow error
Segmentation fault (core dumped) tesseract "data/Apex-ground-truth/eng_62.tif" data/Apex-ground-truth/eng_62 --psm 13 lstm.train
Makefile:262: recipe for target 'data/Apex-ground-truth/eng_62.lstmf' failed

Hi Gabriel.
Thank you for this tutorial.
I was trying to run the code but I'm receiving this error:
Fontconfig error: Cannot load default config file: No such file: (null)
This error appears to be font-related. I've experimented with several fonts but I'm unable to resolve this issue.
Could you help me please?

Hi Gabriel,
Thanks for making this tutorial, I was waiting for it.
I will start taring my model soon. 😍
But how we can fine-tune a model?
Can you please show me how can I combine this new trained file with another model?
Glad you liked it! In this tutorial you can see I actually fine-tuned, I started on the eng.traineddata file from Tesseract and trained it further on a new font, this should be enough for most cases.
@@AstuteJoe Hi Gabriel, when I fine-tune I get a very bad result. I just wanna add some new words and some characters, but the final file that I get is worse than the main traineddata file.
I'm trying to fine-tune an RTL language.
Thanks a lot.
@@farazsoftinfo That's a very different rabbit hole, that's ML techniques, you might be overfitting (training too much) or underfitting (training too little) your model, have you tried generating all the 193k PDFs to train and leaving it to train for a bit?
@@farazsoftinfo I'm trying to do the same thing and the result is a bunch of "mmmoooomom...". Is yours the same?
@@gabriel2011gabriel I tried it for Persian, but I couldn't get a good result. The main models are still better than what I got. When I try to add some new words and fonts I get a worse model. Maybe I should check it more to figure out the best settings that work for the RTL languages.
While running the script 'split_training_text.py'. I am getting the following error:
Fontconfig warning: "/tmp/fonts.conf", line 4: empty font directory name ignored
Could you help me how to resolve this?
I am also getting this.. running as sudo helped a bit still getting this "Unable to open '../tmp/fonts.conf' for writing: No such file or directory"

Thank you for this video. I am now able to train Tesseract to ocr my language data in the Mac. This is working great both in the Linux and the Mac. (But, I am unable to do so because I am getting error "tessdata_prefix not recognized" in the Windows. )
Hello, I am currently stuck. Where did you upload your new font ttf file in the code directory like where should it be place? I have a custom font ttf file that I want to train on?
Hi
Just run:
set TESSDATA_PREFIX="../tesseract/tessdata"
and then run the text2image....
Hello, Can you please explain how to debug the Tesseract code, to get an idea on how the code works ?
Honestly, I think your best bet is cloning the GitHub repo, readings the docs and then delving onto code, just reading it, eventually you'll be better at knowing where to look and after trying hard you might be comfortable and understand it. And I'm pretty sure in the docs you can dump and inspect some intermediary steps debug files, finally, be sure to run it on verbose mode, probably -v. Ah, and you can compile it with debugging symbols too, should help if you want to set breakpoints etc
Helloo is there anyone who tried to learn tesseract polish signs !. I have adjusted this split_training_text for Tesseract 5.0 to create lines of polish set and then teach tesseract. Problem is with font type i think, cause it should know how to recognize those special characters:
Stripped 4 unrenderable word(s): 'unieważnienie SZKOŁAMI NADZIEJĘ, | '
I can share my adjusted script to generate those lines with you if you want. I will try with another font. I tried HvDTrial Fabrikat Mono
Running this on Windows I had to modify the Makefile to make it work
When running your python script, an error occurs:
Fontconfig error: Cannot load default config file
Fontconfig error: Cannot load default config file
Could not find font named 'Waukegan LDO Bold'.
Please correct --font arg.
How can I solve this error? I need to use my unique font "Waukegan LDO Bold.ttf"
I hope you can help me to solve this problem, thank you in advance.
I think that you should install this font in your system first :)
Is tessaract 5 can helpful for detecting only bold text from images
Only experimentation will tell, but Tesseract 5 does perform better some times
I always get an error when I want to use a font, it is installed and can be find by windows and even looking it up works perfectly. When I run the split_training_text.py I get the following Error:
Fontconfig error: Cannot load default config file: No such file: (null)
Fontconfig error: Cannot load default config file: No such file: (null)
Could not find font named 'Quadrant'.
Pango suggested font 'Cascadia Code'.
Please correct --font arg.
I want to train the model on Quadrat-Serial-Regular.ttf but it just won't regognize it. I tried to look it up but can't find it. Modifying the font flag doesn't help since it wants a name but it can't find it even tho it is there, but tbh I don't know where it is searching for the fonts.
The Folder is located on the SSD E: and the operating system is on C: but tesseract and python are in the path of C: so they should get access to it. Please help

@@TheComputerChip I gave up, looked at another method that uses the Google colab and create my own model there it works pretty well. Don't know the video anymore cause probably between then and now I watched approximately 250 vids. Not kidding I don't have a life
@@Bengeljo hahaha no worries. I actually ended up getting this to work. The error doesn’t seem to affect the output oddly enough. As long as it finds the font everything still runs. Currently waiting as my PC generates the images and then I’ll sleep as it trains. On video #3 since starting the image creation! lol

does this also work on windows or do i have to use a different method?
I believe it works, but definitely not every step exactly like in the video. But as far as I remember the Tesseract mantainers highly recommend Linux instead
I tried on Windows, not working very well, pls let me know if you are able to solve it
So I actually followed this through, handy scripts.. However
Seems to have seriously overfit my data. No augmentations? No variance in font size or spacing?
I notice in this video you only actually evaluate your trained model against a ground truth image. This all looks technically correct but as it stands still kinda useless for any practical application?
How's the output if you generate a new text without text2image and run it against that ?
I imagine you could edit the tex2image utility source code to introduce the variance you need, tesseract is open source

I solved this issue 😅
@@Kronzplayz. how you solved it? I got the same issue
@@enriqueortiz5875 solved it: need to run in tesstrain folder:
make leptonica tesseract
make tesseract-langdata
Hi, Gabriel: I am getting this error: at the last training step when I am trying to train a new font called Bender:

did you manage to train tesseract for bender yet?

same to me, have you had a solution yet
@@TuanLe-ve7lm No, sadly I gave up on how to train Tesseract 5. I'm going to try to learn how to train Tesseract 4 because there are a lot more videos on youtube.
@@TuanLe-ve7lm I actually fixed the issue by using Linux. But now I get other errors lol
@@faint.2396 Did you fix your problem ?
I think it could be related with text2image itself. You have to provide path to text2image.exe which in general is located in installed tesseract.
Hi Gabriel, hope you doing well
I ran this command

Hi, were you able to solve this error? If so, how?
When I use the code TESSDATA_PREFIX=.../tesseract/tessdata make training model_NAME=Apex Start_MODEL=eng TESSDATA=.../tesseract/tessdata MAX_INTERATION=100 it's not work, giving an error about the comand TESSDATA=........
someone can help me?
Are you getting "not recognized" error. I am getting the same error on Windows. The exact command works fine on the Mac. Very strange. Do you find a solution?
understood jack shit from this video needs more dumbing down
fr and I did every step the same and I'm getting errors. Why isn't training Tesseract 5 simple as Tesseract 4? And the thing is there's only ONE video on how to train Tesseract 5 and its this one.
