OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect

[VickkyMama]

Hi, I followed the steps on github for implementation but it displayed this - OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'runs/train_base/magicpoint_synth_2023-03-14_13:08:15'

I am running on Conda PyCharm

It works well on Google Colab but I want to run it on my local computer. I have searched online but couldn't get any help.

This is the complete error message. Please help urgently

Solved.

Windows does not support some special characters as filename and the filename had time (:) so I had to change to underscore (_).
It can be changed in the utils.py line 901

from this:

str_date_time = datetime.datetime.now().strftime("%Y-%m-%d_%H:%M:%S")

To this:

str_date_time = datetime.datetime.now().strftime("%Y-%m-%d_%H_%M_%S")
