ModuleNotFoundError: No module named 'tf_slim'

Question

Using Anaconda to try and setup deeplab (https://github.com/tensorflow/models/tree/master/research/deeplab).

I have gotten through a lot of issues by seeing other questions answered but have hit one that doesn't seem to be answered:

when trying to run the "python deeplab/model_test.py" I get:

(base) PS D:\DeepLab\models-master\research> python deeplab/model_test.py

ModuleNotFoundError: No module named 'tf_slim'**

I found some suggestions that this may be environment variable related but mine are all correct: env vars and i refreshed the anaconda window multiple times to make sure the changes were taking place.

I have tf_slim in my folder directory here: C:\Program Files\Python36\Lib\site-packages\tf_slim.

Not sure what to do :( I'm pretty new at this type of installation.

I am on windows 10.

Answer 1

Anaconda by default creates a virtual environment and if you open python via anaconda prompt ,the python executable in the virtual environment is opened. This virtual environment will have it's own set of modules and won't refer to the system level python packages. I suggest you to open the anaconda prompt and type the following command:

pip install tf_slim

Answer 2

I believe the

export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim

is necessary from inside tensorflow/models/research before trying the model test.

HOWEVER, for this particular error, that indicates a missing library, simply doing this worked for me.

pip install tf_slim

Answer 3

Try running

Export PYTHONPATH=$PYTHONPATH:’pwd’:’pwd’/slim
