Unable to find 'extract_gpu' in Dense Flow during optical flow extraction

[PoudelSushmita]

Problem: I'm experiencing an issue when running the bash scripts/extract_optical_flow.sh command. The script appears to be creating folders instead of frames.

Command Run:

bash scripts/extract_optical_flow.sh /home/fm-pc-lt-281/projects/ActionCLIP/UCF-101/Archery /home/fm-pc-lt-281/projects/ActionCLIP/ucf101/Archery 5

Output on terminal:

Extracting optical flow from videos in folder: /home/fm-pc-lt-281/projects/ActionCLIP/UCF-101/Archery
reading videos from folder:  /home/fm-pc-lt-281/projects/ActionCLIP/UCF-101/Archery

And if i check the error.log file to find what could be the possible reason I found:

While running the 'build_all.sh' script, an error was encountered related to the absence of 'CMakeLists.txt' in the Dense Flow directory bash, which may be the reason behind above error but how can i fix it?
