hi, have you solved the problem?

hi, have you solved the problem?

no

I just comment the 'os.symlink(src, dst, **kwargs)' in /root/anaconda3/envs/open-mmlab/lib/python3.7/site-packages/mmcv/utils/path.py

I just comment the 'os.symlink(src, dst, **kwargs)' in /root/anaconda3/envs/open-mmlab/lib/python3.7/site-packages/mmcv/utils/path.py

got it, thank you!

[Asura-Ace]

you should check your folder's filesystem(by 'df -T folder') which supports softlink or not.

Did this work?

File "/miniconda/envs/py36/lib/python3.6/site-packages/mmcv/runner/runner.py", line 252, in save_checkpoint

Find the runner.py ,line 252.Comment the code ' # mmcv.symlink(filename, linkpath) '

Some environments do not support os.symlink so that you can add an argument in the checkpoint_cfg field in config files, like checkpoint_cfg=dict(create_symlink=False).
