tboard_val_imgs folder missing when running test example

[krikru]

When having fixed two previous issues, I get a new crash (still when running python run_nerf.py --config config_fern.txt):

Traceback (most recent call last):
  File "D:/third-part/nerf/run_nerf.py", line 928, in <module>

    raise FileNotFoundError("The directory %r does not exist" % dn)
FileNotFoundError: The directory 'D:\\third-part\\nerf\\logs\\fern_test\\tboard_val_imgs' does not exist

An easy workaround is to manually create the tboard_val_imgs folder in logs\fern_test (I'm running Windows 10; hence the backslash in the path).

Sorry to bother you. I think the reason might be that you rerun the model after deleting the tboard_val_imgs folder and you didn't delete the fern_test folder and summaries folder at the same time?
