Extend DetectionSuite to include Python based detection networks about detectionmetrics HOT 4 CLOSED

I would like to add that list of bounding boxes, detection scores, etc are returned in the form of numpy.ndarray by tensorflow, so inorder to read that in C++, we might have to use numpy's c api also which has ArrayObject available for this purpose.

Hi @vinay0410 ,
the video looks awesome, great job!

I'm having some troubles to make your code work, I'm getting the following error when trying to use the tensorflow backend:

returned tensorflow

my config:
echo $PYTHONPATH
/home/frivas/devel/dl-DetectionSuite/DeepLearningSuite/DeepLearningSuiteLib/python_modules/

Anything else that i'm missing?

I have some questions:

1. Which python version should I use?
2. I have to specify something in the "Net Configuration" box? or just a foo file?

cheers,

Hi @chanfr

Thanks for replying!
I have tested this in python 2.7.

Though, the error seems to be tensorflow import error. Which version of tensorflow are you using?
I have tested it in 1.5.0.
Also could please try importing tensorflow in terminal by typing python and then import tensorflow
See if this error occurs again.
Also, your PYTHONPATH is set to a different location as compared to the directory printed in stack trace here

Traceback (most recent call last):
File "/home/frivas/devel/gsoc2018/dl-DetectionSuite/DeepLearningSuite/DeepLearningSuiteLib/python_modules/tensorflow_detect.py", line 2, in 

Although, that shouldn't cause a problem , but changing that would certainly help in future.

Also, it is necessary to specify something in the Net Configuration, and that can be a foo file since it will not be used.

Cheers

Hi @chanfr,
I have added a commit which will probably fix your issue know, which was regarding importing tensorflow.
It seems as if tensorflow requires sys.argv, when being imported and while it is being called from C++, sys.argv is generally not set.
So, I have added an empty sys.argv.
Please try again and see if it fixes your issue.
I have tested it again on my computer and works great even after this minor alteration.
Also, do add your PYTHONPATH in the python_modules of the updated repository.

Also, I have referenced this fix from here

Thanks!!
