Error while training

[jay98]

I got the camVid dataset as specified in the in the read me file and installed video-decoder

Ientered the following command to start training:
th main.lua --datapath ./data/CamVid/ --cachepath ./dataCache/CamV/ --dataset cv --model ./models/model.lua --save ./Models/CamV/ --saveTrainConf --saveAll --plot

And I got the following error,

Preparing CamVid dataset for data loader
Filenames and their role found in: ./misc/dataDistributionCV.txt

Getting input images and labels for: 01TP_extract.avi

I would really appreciate if anyone would help me with this.

Thank You!

@jay98 can you please check and tell me if you are able to run this script?

@codeAC29 I was able to fix the error by looking at issues in the video-decore git , but now I get the following error

I looked at this issue for the previous fix

And I got the following output when I ran the script you told me to run
