_prroi_pooling.so: cannot open shared object file

I'm trying to run the tracker with a webcam or in a video but it gives this error: ImportError: /home/user/.cache/torch_extensions/py39_cu113/_prroi_pooling/_prroi_pooling.so: cannot open shared object file: No such file or directory and ImportError: Can not compile Precise RoI Pooling library.

Here is my Traceback: /home/user/Documents/Computer Vision/pytracking/pytracking/../pytracking/features/preprocessing.py:109: UserWarning: floordiv is deprecated, and its behavior will change in a future version of pytorch.

Try it by first fixing your path which is "/home/user/Documents/Computer Vision/pytracking/pytracking/" remove the space between "Computer Vision" either by removing the space or adding an underscore. Then check

[vahmelk99]

It isn't the case because path is given with " so it understand the path.

@vahmelk99 Have you solved the problem? Which cuda and pytorch version have you installed ?

[vahmelk99]

No. CUDA Version: 11.6

conda list | grep pytorch: pytorch 1.10.1 py3.9_cuda11.3_cudnn8.2.0_0 pytorch

pytorch-mutex 1.0 cuda pytorch

torchaudio 0.10.1 py39_cu113 pytorch

torchvision 0.11.2 py39_cu113 pytorch

I solved this issue by creating a virtual env and installing pytorch 1.10.0 with cuda 11.1 Keep your current installation and try this in virtual env.
