I don’t understand what should do now? And how to solve this issue! Please help……….
Answers:
base64.encodestring
was deprecated since python 3.1 and finally removed in 3.9
You can compare the official documentation for the base64 library for version 3.8 and 3.9
https://docs.python.org/3.8/library/base64.html
https://docs.python.org/3.9/library/base64.html
I’m not sure exactly how you installed anaconda navigator but i would suggest using the latest distribution of anaconda which includes navigator
This error is caused by nbformat. Check your nbformat with the command ‘pip freeze’, and look for the nbformat version. Most likely your version is anterior to 5.1.3.
Upgrade to that version with the following command:
pip3 install nbformat==5.1.3
or just ‘pip install nbformat==5.1.3’ ; depending on your configuration.
It should fix the issue.
