No module named 'pycocotools' after UPDATE

[ihuanh]

After the update, cannot open TagLab again and it shows up:

Traceback (most recent call last): File "taglab.py", line 78, in from source.NewDataset import NewDataset File "C:\Users\user\OneDrive\Documents\TagLab-main\source\NewDataset.py", line 20, in from pycocotools import mask as maskcoco ModuleNotFoundError: No module named 'pycocotools'

Did anyone found this happening also? How can I solve this problem?

In the bottom part of indatll TagLab: [Known problems and how to solve them If PyQt not work properly under WIndows (e.g. import problems when TagLab is launched) perhaps the Microsoft Visual C++ Redistributable is not installed on your machine. ]

And I Download and install from here instead (https://visualstudio.microsoft.com/zh-hant/vs/features/cplusplus/) install taglab again and it works for new update.

Hi ihuanh,

yes, indeed. After the last update we need to install Microsoft Visual C++ Build Tools and re-run install.py due to a new component used to export dataset in COCO format (pycocotools).

We will update the installation Wiki with this information.

You can also install pycocotools on windows with the following command without having Microsoft Visual Tools installed:

pip install pycocotools-windows

@mlopezp after doing so, did you need to adjust any import statements to reflect the change from pycocotools-windows instead of pycocotools?

In addition, there's also the ability to install pycocotools via Conda, though unless you remove the pip install pycocotools from install.py, it will still attempt to install it via pip.

I followed @mlopezp's suggestion and so far TagLab appears to be working properly. @maxcorsini It might be worth switching to pycocotools-windows to avoid having to install Microsoft Visual Tools and the messiness associated.

Unfortunately, pycocotools-windows it is not available for Python 3.9. But it is a good solution for people using python 3.7 and 3.8.

@Jordan-Pierce I didn't have to adjust any import statements. I am running Python 3.8.10. I haven't had any issues with the installation so far.
