How can I upgrade from Tensorflow 2.0 alpha to beta given the exception: ERROR: Cannot uninstall 'wrapt' - upgrade

Question

When trying to install the beta version of tensorflow 2.0 I am getting the following exception:
ERROR: Failed building wheel for wrapt
Running setup.py clean for wrapt
Failed to build wrapt
Installing collected packages: tf-estimator-nightly, wrapt, tb-nightly, google-pasta, tensorflow

Uninstalling tf-estimator-nightly-1.14.0.dev2019030115:

Found existing installation: wrapt 1.10.11
ERROR: Cannot uninstall 'wrapt'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
What can I do about it?

Answer 1

I also faced this error but you can safely ignore this error.
You can read more about this, here in this issue.
Or, you can first install/update the wrapt package using pip install wrapt==1.11.0 or whatever version TF Alpha requires. Then just continue with TF Alpha installation.
