The doc issue

I run using TSN model according to https://github.com/open-mmlab/mmaction2/blob/main/demo/README.md, the following error occurred.

Please let me know how to fix it.

thanks for your feedback. the bug is due to the outdated config file path in the document, you could solve it by replacing the path with a valid one, which is commonly similar to the original one. we will fix the issue in pr
