Thanks 👍
thank you infinitely
Thanks
Terima kasih
Ia sangat-sangat membantu🤓👍🏻
Hello, I hope you can help me, I have a problem when I type make -j$(nproc), it is giving me "No targets specified and no makefile found. stop", and I followed all the steps successfully
seksa nye nk tulis semua😢😢, great video btw
The following error comes up after typing everything out at the 7:00 mark:
"The source directory "/home/pi/opencv' does not appear to contain CMakeLists.txt"
Why? I followed everything in the video but all attempts to troubleshoot it just lead to other errors. Everything was fine up to that point.
Im having freezing issue while running 'make'command
Im having freezing problem when i run 'make'command
hi why not put all the commands in a text form also.
Thank you
i can't git clone .Can you help me?
works for raspberry pi zero?
I follow all the tutorial but at the end appers ModuleNotFoundError: No module named 'cv2'
looks like I did everything correct up to the last line in Terminal. I entered cv2._version_ I got the following. Traceback (most recent call last):
File "", line 1, in
AttributeError: module 'cv2' has no attribute '_version_'
>>>
Any idea on what I did wrong? thanks
Hi Paul, i got the same issue...do you have the solution of this? Mike
I believe I have the problem because I downloaded and installed the face recognition sw before I downloaded the open CV sw. Still wating for some assistance however I was able th run the facial recognition software successfully.
Thata two underscore on each side of version
maybe a little late, but you have to write "cv2.__version__" with double underscores before and after word "version"
i use pi 4 1gb, when running to 99% host is at that, unknown kernel
i followed all the steps, but it installed opencv only for python2. On python3 it says "no module named cv2"
Hello. We have the same problem. Did you find a fix? :)
i get an error after i do -D BUILD_EXAMPLES=OF .. at the end it says Configuring incomplete, errors occured!
I had the exact same problem try this site www.pyimagesearch.com/2018/09/26/install-opencv-4-on-your-raspberry-pi/ look under RUN CMAKE OPENCV 4 , then the rest of the tutorial should be fine
@@ExoSkelGuy still the same error ;(
I got error in my raspi 3 model b+
"make -j$(nproc)"
There said:
"make: *** No targets specified and no makefile found. Stop."
Please help me
Hi. You can email to us at support@cytron.io for more technical assistance. Thanks
Lo pudiste resolver?
Hello. Installation was accomplished with no errors whatsoever until the testing part, when importing cv 2, it shows that there is no module named cv2. How does one fix this? Thank you :)
