Some times after an update the code written on a previous version might not work as is. For example after update to tensorflow 2.1 a lot of previous codes broke. A quick fix would be to downgrade the version of tensorflow to the one which we are sure it works for. To downgrade the tensorflow in anaconda, we can do the following
Launch anaconda and click on the environments on the left tab and select the environment on which you want to work and search for the package by typing in the text box as shown below.
Click on the green tick mark and then move down to the option "Mark for specific version of installation" and choose the version that is required , click on apply .
Anacdonda will solve the package dependencies and then the following window should appear.
Click on apply that should take care of changing the version of the package.
