When I run train.py, I got an import Error

[Hydraz320]

Traceback (most recent call last):
File "train.py", line 18, in
import commentjson
File "C:\Users\hydraz320\Anaconda3\lib\site-packages\commentjson_init_.py", line 1, in
from commentjson import dump
ImportError: cannot import name 'dump'

May I ask that which os you were using? Thanks a lot.

This seams to be an issue with your commentjson version. I am using Vesion commentjson==0.6.

A work around would be to replace from commentjson import dump with from json import dump. You can't use comments in the config file then. However KittiSeg currently does not have any comments in it, so it will work out of the box.

Hi, I am using commentjson 0.6 as well, but I get the same error. It might be windows (although I'm on Debian 4.9.13-1) and/or python>3.4 related, see https://github.com/vaidik/commentjson/issues/3.

I have used your workaround (simply using json instead of commentjson in train.py) and it does not complain anymore, but it might have led to a different problem. I'll submit a separate issue for that in case it's unrelated.

@WPSanberg
Hello, I've been getting the same error, then it was suggested in the Issue 8 to use Python 2.7, I installed everything for 2.7 and the issue was resolved for me.

[Hydraz320]

Well, I use python2.7 and ubuntu16.04 and get the expected results.

[MarvinTeichmann]

ok. This issue seams to be fixed. So I close it for now.

Regarding commentjson: I properly should look for an alternative if it does not work with python 3.4. In practise this is a minor think. In theory json could be used and/or any wrapper which removes comments.
