Describe the bug

I followed the documentation and went with Option 2 to build my custom dataset. To study how to extract the feature, my dateset include 135 RGB frames which extract from a video in THUMOS14. When I reached step 6, I used tools\misc\clip_feature_extraction.py to extract features from my rawframes dataset. However, I encountered an issue: it produce a .pkl file of 2048 (feature dimension) x 1 (number of features) rather than 2048 (feature dimension) x 135 (number of features equals to number of frames ). How can I use clip_feature_extraction.py to input the rawframes , and then output the RGB features of each frame?
