Thank you @tazu786
The library works fine on Linux systems. It installed on Google Colab which is Ubuntu 18.04 system.

This is OS-specific issue. It will be fixed soon. Sorry for inconvenience. For now, you may use Google Colab and it should work fine.

Thank you @oke-aditya
I managed to install it just with pip install mantisshrimp. Most of the imports work fine except for
from mantisshrimp.hub.detr import *
for which I get

Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'mantisshrimp.hub'

[oke-aditya]

It is working on colab @tazu786 . I will check on windows. The package is not realeased on PyPi so pip install might not work.

[tazu786]

Thank you @oke-aditya , I installed manually and it works.

[lgvaz]

Hello @tazu786 , thanks for reaching out

Did you managed to fix the error at the end?

[tazu786]

Hi @lgvaz , thank you for your great work on this repo!
Not really, I just copied the package manually within the environment lib folder. All the imports work but I haven't tested it yet because of an issue with run_detr, which I posted here https://github.com/lgvaz/mantisshrimp/issues/39#issuecomment-646096910

[lgvaz]

I'll check the issue and get back to you asap 😄

[lgvaz]

@oke-aditya is this the error related to pycocotools you were talking about?

I updated the install instructions and successfully installed on macOS. Can you still reproduce the error on windows?

[oke-aditya]

Yes still error is prevailing

[oke-aditya]

Yes still error is prevailing. I will fix it up.

[lgvaz]

Meanwhile @tazu786 , I added a new example to colab, everything is working no additional setup required

be sure to check it out 😁

[oke-aditya]

PR opened for this. #95

[oke-aditya]

The problem is not with pycoco tools thats another issue. It isn't our problem pycoco tools do not support windows.
It was simple file encoding utf-8 which linux assumes by defualt and hence CI / Colab / MacOS built it easily.

[oke-aditya]

Can you try again from the original method suggested in the readme. Setup.py should work now. I am able to install as per README.md file by running

pip install git+git://github.com/lgvaz/mantisshrimp.git

[tazu786]

both the installation and the new colab work fine! Thank you both! @oke-aditya @lgvaz
