RuntimeError: cannot join current thread

[Rahul-Venugopal]

I have followed the instructions given in the page and have tried to visualize the results using following code
### with video_sheeping.py

python video_sheeping.py figure_skating/models/resnet_50_augmentation_no_noise_75_100/Resnet50SheepLocalizer_97305.npz \log \-i videos/validation_data/video.mp4 \ -g 0 \ -o validation_data/analyzed_video.mp4

And I get the following error

0%| | 0/5 [00:00<?, ?it/s]

Can anyone suggest a possible solution ?

Okay,

for the first error you have two problems:

• Could not find encoder for codec id 27: Encoder not found You do not have the correct codec on your PC to load this image with openCV
• render_scores=args.discriminator is not None my bad, I should have fixed it now^^

The second error should now also be fixed...

[Rahul-Venugopal]

Thanks for replying . Yeah now its solved .Thank you

[Rahul-Venugopal]

Hi ,
I have came across another problem when using my GPU. It works fine when I run it without gpu . But I have following problem using GPU . Maybe anyone had similiar issues before , please help.

My cupy and chainer versions are as follows

Chainer: 4.1.0
NumPy: 1.15.4
CuPy:
CuPy Version : 4.1.0
CUDA Root : /usr/local/cuda-9.0
CUDA Build Version : 9000
CUDA Driver Version : 9020
CUDA Runtime Version : 9000
cuDNN Build Version : 7104
cuDNN Version : 7104
NCCL Build Version : 2104

When I execute

python image_sheeping.py figure_skating/models/resnet_50_augmentation_no_noise_75_100/Resnet50SheepLocalizer_97305.npz \log -i figure_skating/evaluation_dataset/test_images/22.png -g 0 -o validation_data/images/analyzed

Error message I am receiving is

In requirements.txt it is asked to install cupy==4.1.0 and as per this link , it is recommended to install cupy-cuda90 if I want to enable cuda .
Can anyone help me to solve the error ?

[Bartzi]

Hmm, I don't exactly know what might cause this error, but just to be sure: Is the image you are using a grayscale image, or is it a RGB image?

[Bartzi]

Installing cupy, using the requirements.txt file should work out of the box, as cupy will be compiled on your system for your CUDA Version, so as long a CUDA compiling is working on your machine, I'd recommend to compile cupy directly on your system using pip.

[Rahul-Venugopal]

Okay......I am using RGB image and it works well if I am compiling it without gpu (i meant with flag g = -1) . I will check again. Thanks for your reply. Will update here if I am able to solve the problem.

Again , as per this link , i cannot use h264 encoder if I install open-cv using pip. Did you actually build open-CV manually or did you install it by pip ?

[Bartzi]

Hmm, I think I installed openCV via my package manager and also via pip.
