install tensorflow 2 problematic

Question

I would like practicing tensorflow 2, but my tries to install it in an anaconda environment failed.

My question is: how do you install tensorflow 2 ? If it can be done in an anaconda environment it seems to me more convenient. I don't need to understand the error message below as long as I can use tensorflow 2.

• First, I found an installation with pip, not conda

• Second, pip gives me a lot of errors: each time I have the feeling I turned around one, another shows up... The best I did, I think is (in a py36 environment): pip install --upgrade --ignore-installed wrapt tensorflow==2.0.0-beta1. Indeed, after having uninstalled tb-nightly, notebook & jupyter, this command runs without apparent error/warning. However, an import tensorflow in python gives me this error:

Answer 1

The beta is pre-release, not stable yet, so you have to use the --pre flag

pip install --pre tensorflow==2.0.0-beta1

Answer 2

Probably you have the same problem issued here.. you can try to solve this upgrading your MacOS system o trying to install the tensorflow inside the virtualenv that you will use for your code

Edit:

to install the package inside you virtual environment (anaconda in this case) you need to activate the env you already create (refer to anaconda docs to make it) and use

$ conda activate myenv
(myenv) $ pip install tensorflow
