Models: Does object detection API has a plan to migrate to python3

[irmowan]

I have to use python3 on object detection API for project. But there is many conflicts when I use python3. Does API has a plan to migrate to python3, as python2.7 will not be supported soon?

I managed to get the object detection API in Python3 by simply using the 2to3 official Python conversor and patching a few parts of the code (I don't remember all but I remember to at least have to manually patch https://github.com/tensorflow/models/blob/master/research/object_detection/utils/config_util.py#L326 ).

It should be pretty straightforward, just run the 2to3 conversor and fix the exceptions that you will be encountering.

4844 someone try to do so without any success, @daavoo could you have a look please?

[daavoo]

@TedLLH #4844 tried to covert the entire models/research. I have not tried that, I managed to convert models/research/object_detection which was what I needed. The errors in #4844 are not from the object_detection module

[TedLLH]

@daavoo i tried with _models/research/object_detection_ and it failed. The error was:

TypeError: Expected float32, got 'Loss/BoxClassifierLoss/localization_loss' of type 'str' instead

which was mentioned #4832 , it seems like I will have to stick with python2 at the moment until they fix the issue......

[TedLLH]

Nope, even with python2, still does not work and encountered the same error, right here: #4832

@TedLLH You can try my solution at https://github.com/tensorflow/models/issues/4832

hey @daavoo do you mind posting the Python-3 compatible object detection library as a separate repo online so that the open source community can make use of it?

I second the motion to port the Object Detection API to python3!

Can someone try this? Im too busy right now to do it but it seems to work with py3.6!
