Why does tensorflow version 2.5 and above work and 2.4 and below not?

[courtlanda]

I needed to use the older version of tensorflow to work with. https://github.com/hunglc007/tensorflow-yolov4-tflite The repository, as it uses version 2.3, and trying to use the last version 2.6, I got a mistake in converting from tf to tflite. But by setting tensorflow 2.3, and just importing it, I got this kind of mistake column:

Then I tried 2.2 and 2.4, but they made the same mistake, and then I fixed 2.5, which worked well, but it didn't work.

I redesigned the anacondu, all the vs c++ libraries and the cudnn version of the table on the tensorflow, but nothing changed.

On the tensorflow site, I didn't find any mistakes with that code.
What's the problem?

Answer for those who face a mistake DLL load failed with error code 3221225501 while importing _pywrap_tensorflow_internal

This error arises when attempting to implement AVX instructions in processors that do not support the extension of AVX. Library _pywrap_tensorflow_internal meets with AVX support from 1.6.0.

If you've faced such a mistake, there are three ways to solve the problem:

1. Find a computer with a processor that supports and works on AVX.
2. Find Tensorflow without AVX
3. Gather TF on your own car.
