Keras-retinanet: colab ModuleNotFoundError: No module named 'keras_retinanet.utils.compute_overlap'

[duhithas]

Im training my custom-dataset using COLAB Notebook ,
Refered to FAQ
unable to run the below command
!python keras-retinanet/setup.py build_ext --inplace

running build_ext
cythoning keras_retinanet/utils/compute_overlap.pyx to keras_retinanet/utils/compute_overlap.c
error: /content/keras_retinanet/utils/compute_overlap.pyx

However I have uploaded compute_overlap.c file from my local system , but when I run the file train.py with the specified path it gives this error below

This error is handled in the FAQ.

I misread the first part, seems you can't build the extension. Do you have a longer error than this? It's not saying what is going wrong.

[duhithas]

No there are no much details about this error..

Could you share a screenshot of your terminal when trying to compile this extension ?

[duhithas]

apologies for the delay ,
PFA as requested
As in the i marked the compute_overlap.c file

[hgaiser]

I think you're sending it as an attachment, but that doesn't seem to work.

[duhithas]

Hope you would be able to view now

[hgaiser]

Sounds like it could be an issue related to colab. Could you try on your own system to see if the extension can be built there.

[duhithas]

Yes i have , It worked and hence I was able to create compute_overlap.c as i have marked

[hgaiser]

Is that the version you uploaded to colab? Depending on your system libraries that might not work properly. Could you try it on a clean clone of keras-retinanet?

[duhithas]

I was able to run my custom dataset using keras-retinanet in my local system , I worked fine ,
Im trying to implement the same in colab ,
However I have tried thrice with a clean clone of keras-retinanet

[duhithas]

unfornately I was unable to find a way to build the extension in colab

[hgaiser]

You can try to use the python version of the cython code, then you don't need the extensions:

https://github.com/fizyr/keras-retinanet/blob/0.3.1/keras_retinanet/utils/anchors.py#L232-L256

[duhithas]

kindly check above , it uses the python version ,
kindly guide me if im wrong

[hgaiser]

You're now doing custom stuff, it's more difficult to support that. By the looks of it you're still trying to import the compute_overlap module, but I'm guessing you just added it to the anchors.py? You don't need to import compute_overlap then..

[duhithas]

Thank you hgaiser for you time and assistance
I was able to build the extension , by navigating to the folder keras-retinanet ,
earlier I was executing it with the absolute path, but now I executed in the current folder having setup.py

[nosa999]

I have this error :(

[hgaiser]

You can't pass a link as csv file, it needs to be a file...

[nosa999]

I did it like duhithas

[nosa999]

and i have this waning when i did "pip install . --user" command in ubuntu and in colab too.

[duhithas]

kindly run this command before you could run pip install . --user
!cd keras-retinanet && pip install . --user
