I tried running the following script and got this error. Can you please guide how to fix it? Thanks a lot.

I am using your docker file for running the script. Also, there was a typo in the script that I have fixed it below:

  #blender_start_file = f'{code_dir}/1.blend'
  blender_start_file = code_dir + '/1.blend'

^^ error before fix:

root@ada:/home/posetrack# python blender_main.py 
  File "blender_main.py", line 47
    blender_start_file = f'{code_dir}/1.blend'
                                             ^
SyntaxError: invalid syntax

Hi, I have the same issue. I think that is because if you look at the folders specified in dataset_info.yml in the docker container, they are empty. Did you put random images there to solve it or what?
