So glad I found this. You explained it very clearly, and I could follow along and get a test layer going in my account. Now to figure out how to automate this ...

[@felipetmota]

Simple, fast, and shows many tips in the video. Normally I was getting errors after creating the .zip in the windows, not on WSL. Top man!

[@brittanymorris5326]

Just wanted to send a big thanks for this! I spent two days figuring out why I was getting the import module error. I tried zipping it in different ways and had no luck. I'm new to this so I was stuck. Until I say this video and the comment below pip install requests "urllib3

[@ImChrisCastro]

Glad to hear you're trying something new and you were able to get unstuck! I'm going to add that command information to the pinned comment. Thank you for the feedback on that, Brittany!

[@SunilMakkar97]

dude its so hard to find a great video on this topic... great job!

[@ImChrisCastro]

Sorry! My powershell window was very small and probably hard to read lol. Here are the templated commands you want to run for this process, if you are using Python:
Terminal Steps:
mkdir python
cd python
pip3 install [library-name-here] -t .
cd ..
zip -r python.zip python
ADDITIONALLY, another commenter let me know that the command 'pip install requests "urllib3

What about heavy libraries? Like Spacy.

[@mumo5154]

[@ImChrisCastro]

Woo!!

[@user-ri7cm4ob1e]

Hi May i know how you are connecting to your shell before creating directory . please comment

[@user-mj5vy3vk7r]

thanks buddy❤

[@genewachtel5900]

Hi Chris I spent all day trying to figure out how to install packages. I found your video and was hoping it would be the solution. I followed each step, but still get errors when trying to install pandas and run. Is there any common issues that you can think of not covered in the video?

[@AndersonOozie13]

Have you been able to make a layer for pyodbc that works with mssql server? The latest I see that anyone has made is for python 3.9, but I can't for the life of me get it to work with python 3.11

[@maximpobihun5469]

should it be 1 layer per library or can be multiple libraries per one layer?

[@ImChrisCastro]

Great question! My current understanding is that you can have as many libraries as you want for a single layer (assuming the libraries file size does not exceed 250 MB - docs.aws.amazon.com/lambda/latest/dg/invocation-layers.html). However, my organization preference is to isolate a single library into a single layer.

[@gerardoluisbv]

Hi! can a use Boto3 and Request together in this Layer?

[@ImChrisCastro]

Yes absolutely! You can use both. Something to keep in mind, you don't need to create a layer for boto3 as that is automatically available in the AWS lambda python environment. However, you would need to create a layer in order to use the requests library.

[@gerardoluisbv]

@@ImChrisCastro Thanks Chris!

[@judyatpit]

saved my many hours - mine package name was not python and I could not tell where the problem is

[@ImChrisCastro]

Wow, that is great to hear. Glad I could help, Judy!

[@user-mk6gd9uy8b]

That was helpful 🫡

[@tarungoel22]

It seems you are typing for yourself. We cannot see anything that you are typing . God knows who you are making this video for

[@ImChrisCastro]

I am making the video for anyone and everyone interested! and yes, haha very small typing indeed!
I pinned a comment detailing what I typed, but I will paste it here as well:
Terminal Steps:
mkdir python
cd python
pip3 install [library-name-here] -t .
cd ..
zip -r python.zip python
