Troubleshooting pycocotools installation

Question

I'm trying to use object detection models from Tensorflow and need to get pycocotools installed. I'm doing this from a python (3) virtual environment on a Windows 10 machine. There seems to be some known issues around getting this working on Windows, and I'm pretty sure I've tried them all.

I've tried pip-installing pycocotools, with this error (fails building wheel):

(env) PS C:\Users\la01043601\ML_CameraVision\humanDetection> pip install pycocotools

I've tried the fix from Phil Ferriere's repository (still fails building wheel, something with math.h file not found):

I've tried installing Visual C++ Build Tools (2015 version recommended by many other answers), but got the error that it was unable to find/download setup package, so I've made sure I have updates to the 2019 build tools, and they are added to my path. Error I was getting is like this one. I also followed the video at the bottom of that solution and it didn't help.

I've tried using the suggested windows install for pycocotools (pycocotools-windows), which gives the following error:

(env) PS C:\Users\la01043601\ML_CameraVision\humanDetection> pip install cocoapi-windows
ERROR: Could not find a version that satisfies the requirement cocoapi-windows (from versions: none)
ERROR: No matching distribution found for cocoapi-windows
(env) PS C:\Users\la01043601\ML_CameraVision\humanDetection> pip install pycocotools-windows
ERROR: Could not find a version that satisfies the requirement pycocotools-windows (from versions: none)
ERROR: No matching distribution found for pycocotools-windows

Python and pip are on my Windows path. I gave up on one tutorial due to this, just to find the next one has a pycocotools dependency too.

(Also accepting suggestions for Tensorflow object detection tutorials that do not use pycocotools! Need a decent tutorial because I'm a beginner).

Edit: Have now also tried running the setup.py file the following way, still having issues with not finding a math.h file...

Edit edit I forgot to mention that in the past couple days I also tried troubleshooting the math.h error, which suggests switching an include statement from "math.h" to "cmath", and using "quotes" instead of angle brackets, and since this happens when installing from a downloaded repo I even forked the repo the made the change on my version to download from there. Error as follows (now related to a missing 'crtdbg.h' file and I don't understand how everything works under the hood in Build Tools):

I managed to install pycocotools only after downloading the installer from this link and installing these:

me too! I ran "pip install pycocotools" on Linux, same error like this:

ERROR: Could not build wheels for pycocotools which use PEP 517 and cannot be installed directly

I solved the problem by conda install pycocotools -c conda-forge

ps: python version==3.7.12

after everything failed, I installed visual c++ build tools using the link below

Visit https://myvs.download.prss.microsoft.com/db/mu_visual_cpp_build_tools_2015_update_3_x64_dvd_dfd9a39c.iso?t=36429cde-dc63-4657-8114-1c74ae0da9bf&e=1645739068&h=e153f9afa2fa5fd4ffae5a1cc714a2ab704115af952dfb82e1761e5553c7999a&su=1

after it has downloaded open it and run the setup file, everything should run smoothly.

Then in your environment run this code:- pip install cython

then this one:

pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI

that should work, I am using TensorFlow version 2.3, Python 3.8

You may need to install:

sudo apt install python3.9-dev

Place another python version if you need 3.8 etc. Then pycocotools is installed correctly, helped in my case when "Python.h" was not found.

Don't Forget to Restart your pc after install visual c++ build tools, in my case everything not working until I restart my PC after installing the build tools.
