Tensorflow Object Detection API - ImportError when I try to run model_builder_test.py

Question

I am creating a custom object detection model using Tensor Object detection API. I installed everything as mentioned in this notebook and following the same steps as mentioned in this notebook but when I try to run model_builder_test.py file

import os
os.environ['PYTHONPATH'] += ':/../models/research/:/../models/research/slim/'
!python object_detection/builders/model_builder_test.py

I get the following error:

RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

I'm using python 3.7.10 and tensorflow 2.6.0 on Intel OneAPI Devcloud. Please help me to solve this error.

You may need to modify your `numpy` version. Does this help: https://stackoverflow.com/questions/20518632/importerror-numpy-core-multiarray-failed-to-import ? It's a post about the same error you're getting. — TC Arlen, Aug 26 '21 at 19:22

Try this,

pip uninstall numpy

Then,

pip install numpy

For specific version of numpy,

pip install numpy==1.8

The error is because you might be having a version of numpy that is incompatible with the version used by the tensorflow object detection API. To solve this issue you can upgrade numpy to the latest version with the below command.

pip install -U numpy
