Problem Description:

Error reporting

analyse problem:

1. I installed both mmcv and mmcv-full. In fact, mmcv is a simplified version of mmcv-full. So you only need to install one.
2. Secondly, I uninstalled mmcv-full and still got an error. I thought it was a problem with the mmcv version.
3. However, the mmcv installed through the cuda version queried by nvidia-smi is incorrect, considering that the cuda version is incorrect.

Solution:

1. Uninstall the installed mmcv and mmcv-full

pip uninstall mmcv
pip uninstall mmcv-full

2. Check the versions of cuda and torch

python -c 'import torch;print(torch.__version__);print(torch.version.cuda)'

The result is as shown below:

It can be seen that torch=1.12.1, cuda=10.2

3. Query the command to download the corresponding mmcv version

Query mmcv installation command

Click the ↑ hyperlink and select the corresponding torch and cuda for query, for example:

Then copy the statement to the command line and run

The installation is successful and then running is successful!
