AssertionError: test.csv dir not found

Hi,

I am just trying to use SlowFast to perform inference on my own videos using the pre-trained models. I have updated the config to include the `DEMO` key and its relevant details. I am using this `'configs/Kinetics/c2/C2D_NOPOOL_8x8_R50.yaml'` config.

I run this command to perform inference: `!python tools/run_net.py --cfg config.yaml`
But I keep getting the above error.
