I ran through the TensorFlow object detection installation on Windows.

After successfully installing TensorFlow object detection,
I ran following command to test, and receiving error below. How can this be fixed?
python object_detection/builders/model_builder_test.py
Error: Traceback (most recent call last): File "C:\TestImage\models\venv\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 64, in from tensorflow.python._pywrap_tensorflow_internal import * ImportError: DLL load failed while importing pywrap_tensorflow_internal: The specified module could not be found.

Currently using Python 3.8 with latest tensorflow, with tensorflow-cpu
You need to install the C++ redistributable mentioned on the install page before installing TensorFlow so that TensorFlow can use it to generate code at install time.
I'm not an expert but it sounds like this was key:
The pywrap_tensorflow_internal.py module you are missing appears to me to be a SWIG-generated python interface to a C++ library, or something of that nature. My guess is, that file gets generated when you install TensorFlow (it reminds me of how some Ruby gems have to compile C++ when you install them, for whatever that's worth). Since you don't have that generated file, my guess is that the C++ package mentioned on the TensorFlow install page is needed for that code generation, so you need to have the C++ package installed before installing TensorFlow.
Totally a guess, but perhaps you installed the C++ package after TF. In that case, you should be able to uninstall TF, install the C++ package, and then install TF again.
Maybe a lingering question is if there were any indicative error messages on installing TF about the missing C++ package and if not, maybe there should be.
