OpenCV error with actionrecognition

Hi,

When I run this code in actionrecognitionnet: !cd tao_toolkit_recipes/tao_action_recognition/data_generation/ && bash ./preprocess_HMDB_RGB.sh $HOST_DATA_DIR/raw_data $HOST_DATA_DIR/processed_data

I get this error:
hello/data/raw_data
hello/data/processed_data
Preprocess convert_dataset
[ERROR:0@0.004] global /io/opencv/modules/videoio/src/cap.cpp (164) open VIDEOIO(CV_IMAGES): raised OpenCV exception:

OpenCV(4.6.0) /io/opencv/modules/videoio/src/cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can’t find starting number (in the name of file): hello/data/raw_data/convert_dataset/* in function ‘icvExtractPattern’

f cnt: 0.0

I am not sure what I need to do. I followed the jupyter notebook and downloaded the appropriate files.

Thanks
