[FIXED] jupyter notebook showing this message, ImportError: cannot import name 'encodestring' from 'base64'

Issue

I am new to python and jupyter notebook and I am using windows. Recently I installed Anaconda Navigator 2.3.1 and the python verson 3.9.13 on my computer. After entering the command jupyter notebook on the command-line, my browser doesn't open jupyter notebook, instead that showing me this error message:

    from base64 import encodestring
ImportError: cannot import name 'encodestring' from 'base64' (D:\Anaconda3\anaconda3\lib\base64.py)

I don't understand what should do now? And how to solve this issue! Please help..........

Solution

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
