我无法在 Google Colab 中测试 Tensorflow 对象检测 API 的安装

Question

I'm just starting to learn how to use the ML models in the Tensorflow Object Detection API on Google Colab and so I'm trying to follow the documentation very carefully. After installing the libraries and packages, I'm testing the installation using the command from https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html :

python object_detection/builders/model_builder_tf2_test.py

But I get the following error:

Traceback (most recent call last):
  File "object_detection/builders/model_builder_tf2_test.py", line 24, in <module>
    from object_detection.builders import model_builder

Even after importing keras version 2.0, it still not working, what I can do to solve this issue, thanks

Answer 1

Solved it: tensorflow version 2.5.0 is not compatible with the code provided. I had to install 2.8.0 so that it will work
