I solved the problem!

This is an error that can occur when cloning a repository using the git clone command.

This repo contains large files. However, when I run the git clone command, sometimes it doesn't download properly.

Therefore, when I git clone, in my case, the "mask_rcnn_rat_cfg_0005.h5" file is not downloaded correctly, and a small file of approximately 100 bytes is downloaded incorrectly.

I found a problem while looking at the size of the files!

1. First, delete the problematic "mask_rcnn_rat_cfg_0005.h5" file.

rm -rf ./mask_rcnn_rat_cfg_0005.h5

2. Download the original file by accessing the address below using the wget command or another method. (Address may change later)

wget https://media.githubusercontent.com/media/nhalle/rat-openfield-maskrcnn/master/mask_rcnn_rat_cfg_0005.h5

3. Now run the command below and it should work!

python analyze_video.py ./video/Video1.mp4 test1 20
