ImportError: cannot import name 'deepmac_meta_arch' from 'object_detection.meta_architectures'

1. I try to run this file

https://github.com/tensorflow/models/tree/master/research/object_detection/builders/model_builder_tf2_test.py

2. Describe the bug

Bug Happens when I try to run the model builder tf2 test from an other environment.

I created my first environment called P0kerv2, on it model_builder_tf2_test.py run well.
But when I try to run model_builder_tf2_test.py on an other environment (ProjetsPython) it does not work.
On the error message it show the wrong path
ImportError: cannot import name 'deepmac_meta_arch' from 'object_detection.meta_architectures' (C:\P0kerV2\ models\research\object_detection\meta_architectures_init_.py).
P0kerV2 should be ProjetsPython so it seems to be stuck on the first env I created.

3. Steps to reproduce

run
python object_detection/builders/model_builder_tf2_test.py

##3.1 and then the prompt output is :

[2021-09-21 00:06:46.804203: I tensorflow/stream_executor/platform/default/dso_loader.cc:53] Successfully opened dynamic library cudart64_110.dll
Traceback (most recent call last):
  File "C:\Users\Dorian\anaconda3\envs\ProjetsPython\models\research\object_detection\builders\model_builder_tf2_test.py", line 28, in <module>
    from object_detection.meta_architectures import deepmac_meta_arch
ImportError: cannot import name 'deepmac_meta_arch' from 'object_detection.meta_architectures' (C:\P0kerV2\models\research\object_detection\meta_architectures\__init__.py)]

##4. What do I think
I think that it try to access to :
C:\P0kerV2\models\research\object_detection\meta_architectures\__init__.py
and not to :
C:\ProjetsPython\models\research\object_detection\meta_architectures\__init__.py

But I don't understand why...
