But under the path, the image is already exist.I tried to add a print in front of the line 47 in detection_utils.py, but it can print the right path.

Each time the error occurs, the wrong file is not the same.

I have the same issue when trying to train the sample_medium file

[nujhat-tabassum]

I am having the same issue. I am eagerly waiting to find the solution to this problem.

I'm faced with the same issue, did anyone find the solution??

SOLVED: you need to update the data_root in the robotcar_mapper python file to your file path.
