Issue with running model_optimizer install_prerequisites_tf2.sh

Hi everybody! I want to use the Openvino_2021 model_optimizer with a .pb file that i created with Tensorflow 2. I get a error when  running the install_prerequisites_tf2.sh file. I followed the requirements in the "requirements_tf2.txt" file and installed tensorflow(Version2.2), networkx, numpy, test-generator and defusedxml in my conda environment

How can i solve this issue? Thanks for your help

Greetings,


Did you tried to install Tensorflow 2.0 in your system manually?

sudo -h pip3 install tensorflow==2.0


Install this manually and try to run the installation script again.


Sincerely,

Hi.

Thanks for your answer!

I did install it manually. To test your suggestion I uninstalled tensorflow first. Then i tried it with "sudo -h pip3 install tensorflow==2.0" but it didn't work (Screenshot1). Then i tried "sudo pip3 install tensorflow==2.0" without the -h flag - This gave me a warning "Could not find a version that satisfies the requirement tensorflow==2.0" (Screenshot2). After that i tried "sudo pip3 install tensorflow==2.0.0b1" -> This was successful as you can see in Screenshot3.   I then tried to run install_prerequisites_tf2.sh again but i got the same error again (See Screenshots 4+5).

In a different environment I installed tensorflow 2.3.1, but this does also not work with install_prerequisites

Please give me advice on what to do, i really need this to work.

Kind regards Daniel

As of October 2020:

  • Tensorflow only supports the 64-bit version of Python
  • Tensorflow only supports Python 3.5 to 3.8

So, if you're using an older version of Python or a 32-bit version, then you'll need to use a different version.


Plus this might be useful for you: https://appuals.com/could-not-find-a-version-that-satisfies-the-requirement-for-tensorflow/


As for now I'm using Python 3.6 and it works with Tensorflow 2.

Hi.

Thank your for your answer and the link you sent me.

I can confirm that i have 64-bit Version installed and i have Python 3.7 - so it really should work - but sadly it doesn't.

I tried again today with a different PC and there i could run the "install_prerequisites_tf2.sh" file without a error. So i can work with this solution for now.

Very strange that it doesn't work on my main PC since my approach didn't change.

Kind regards Daniel

The unable to resolve host in linux usually happens after host-name changed. (https://www.youtube.com/watch?v=cvazO6i0i5s)


pip could also be the the reason as what these users had been facing: https://github.com/tensorflow/tensorflow/issues/31939
