Hi, thank you for your opensource.
Several days ago, I used your source code and successfully run the train.py file. However, without any change of the code, I can't run it again and meet these error. So I installed your source again and also try on other computers, even transport your file to new mmsegmentation framwork, but still met the same error. I suppose the errors come from the change of mmcv. But I really don't know how to modify the code. Could you please tell me how to modify it. The errors are(I am sure I put the RUGD data in the right place):

"""

This is strange -- have you made sure that "data/rugd/train_ours.txt" exists?

from ganav-offroad.

Yes, I put them in the right place and ran it successfully once but failed days later.

Besides, I also tried other methods:

1. I changed the data_root from a relative root to an absolute one, meaning
   from data_root = 'data/rugd' to data_root = '/home/linchangyi/Final_Project/SSDMUE/mmsegmentation/data/rugd'
   but still met error: No such file or directory: '/home/linchangyi/Final_Project/SSDMUE/mmsegmentation/data/rugd/train_ours.txt'

2. I chose not to use split but directly change the img_dir and ann_dir to the specify one, and deleted split="train_ours.txt",
   like:
   
   but still met error: No such file or directory: 'data/rugd/creek'

3. I installed your code in other computers from one step to one, but still met the error like the first one.

This is really strange. I just made a fresh git clone and it seems that it's working properly for me.

There are a couple of suggestions:

1. Have you make sure that the directory is not empty here, or the file indeed exists -- "home/linchangyi/Final_Project/SSDMUE/mmsegmentation/data/rugd/train_ours.txt"? This error seems quite straight forward -- the code could not find this file.
2. It's possible that the mmseg is messed up in the environment. Have you tried using conda env and tried creating a fresh env for GANav? Previously when I put different versions of my code in different places, I have to run "pip install -e ." to make sure that it's using the repo I intend to.
3. Have you made sure that you pulled the latest version of the code?

Thanks for your trying and suggestions.
I will try it again in new environment.
