Hi,i run this project in google colab and install mmaction2 to run build_file_list.py, but i encounter the error No module named 'mmaction.datasets.utils'. I know is the mmaction problem. I wonder how to generate file list in mmaction2

hello @dandingol03 .
I have also encountered this problem, which has just been solved. Maybe you need to uninstall your mmaction2, and then install mmaction according to the following steps.
