@SINGHBP29 commented on GitHub (Feb 7, 2025):

Use the Below command to solve the error

pip install --upgrade pip
pip install torchvision
pip install torchvision==0.21.0
pip install torchvision==0.21.0 --index-url https://download.pytorch.org/whl/cpu
pip install torch==2.2.0 torchvision==0.17.0 --index-url https://download.pytorch.org/whl/cpu
pip install --upgrade torch torchvision
pip install torchvision==0.15.2
pip install git+https://github.com/facebookresearch/pytorchvideo

These commands show attempts to:

Upgrade pip.
Install the latest torchvision.
Install specific versions of torchvision (0.21.0, 0.17.0, and 0.15.2).
Install torchvision with a specified index URL for CPU.
Install PyTorch and torchvision together with a specified index URL for CPU.
Install PyTorchVideo from GitHub.

@SINGHBP29 commented on GitHub (Feb 7, 2025): Use the Below command to solve the error 1. `pip install --upgrade pip` 2. `pip install torchvision` 3. `pip install torchvision==0.21.0` 4. `pip install torchvision==0.21.0 --index-url https://download.pytorch.org/whl/cpu` 5. `pip install torch==2.2.0 torchvision==0.17.0 --index-url https://download.pytorch.org/whl/cpu` 6. `pip install --upgrade torch torchvision` 7. `pip install torchvision==0.15.2` 8. `pip install git+https://github.com/facebookresearch/pytorchvideo` These commands show attempts to: * Upgrade pip. * Install the latest torchvision. * Install specific versions of torchvision (0.21.0, 0.17.0, and 0.15.2). * Install torchvision with a specified index URL for CPU. * Install PyTorch and torchvision together with a specified index URL for CPU. * Install PyTorchVideo from GitHub.

I think it's better to fix the core problem than trying to play with package versions, since it is likely to cause other problems. The problem is in basicsr package and it's fixed already. Install it using

pip install basicsr-fixed

instead of pip install basicsr

@drkovalskyi commented on GitHub (Mar 29, 2025): I think it's better to fix the core problem than trying to play with package versions, since it is likely to cause other problems. The problem is in `basicsr` package and it's fixed already. Install it using ``` pip install basicsr-fixed ``` instead of `pip install basicsr`

I had to use both solutions,
pip install basicsr-fixed
thanks @drkovalskyi
and this.
thanks @abdulkarim1422
