SyntaxError: invalid syntax

[liuxufenfeiya]

the same error as#875,but use the resulotion of #820 was not work(change the cfg.pretty_text to cfg.text,or change the cfg.text to cfg.pretty_text,return the same error)
my train command was
./tools/dist_train.sh configs/recognition/slowfast/slowfast_r50_video_4x16x1_256e_kinetics400_rgb.py 1 --resume-from ckpt/slowfast_r50_video_4x16x1_256e_kinetics400_rgb_20200826-f85b90c5.pth

the error code was:

Maybe you should use --load_from instead of --resume_from. Resuming from a released checkpoint doesn't make sense.

sorry,it didn't work.

./tools/dist_train.sh configs/recognition/slowfast/slowfast_r50_video_4x16x1_256e_kinetics400_rgb.py 1 --load-from ckpt/slowfast_r50_video_4x16x1_256e_kinetics400_rgb_20200826-f85b90c5.pth

error was:
train.py: error: unrecognized arguments: --load-from ckpt/slowfast_r50_video_4x16x1_256e_kinetics400_rgb_20200826-f85b90c5.pth

You should set the argument load_from in the config file.
