2 years ago I managed to resolve this issue. Here is an update for anyone else who might face the same issue in the future:
In general, updating the older versions of Anaconda can be cumbersome and might lead to several technical challenges. The easiest and the most efficient solution is to first uninstall the older version of Anaconda Navigator. Then install the latest version.
I performed the following steps (Windows user):
- Followed the official guidelines for Anaconda uninstall (Option B for full uninstall) in 2 steps:
STEP 1: Use Anaconda-Clean to remove all traces of the configuration files and directories, write in Anaconda Prompt:
conda install anaconda-clean
anaconda-clean --yes
STEP 2: Simple remove of all related files (I followed these extra guidelines on Stackoverflow):
- In Windows Explorer: find and delete any environments and packages related to Python/Anaconda/IPYNB
- In Registry: Start > Run > Regedit >HKEY_CURRENT_USER > Software > Python > remove folders: Anaconda & PythonCore
- Delete related folders, cache data and configurations from Users/user
- Delete from AppData folder from hidden list
- In Control Panel: Add or Remove Programs > Uninstall Anaconda (this should be the last step)
It's important to follow these steps as provided in sequence. It will clean every Anaconda file on your system.
- Install new Anaconda from: https://www.anaconda.com/products/individual
Hope this is helpful!
I am facing this issue when trying to open Jupyter notebook from Anaconda. I tried searching for a resolution but nothing has worked so far. The issue appeared when I executed this code to update Anaconda from version 1.9.12 to the latest:
conda update --allTraceback (most recent call last): File "C:\Users\rafal\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in from notebook.notebookapp import main File "C:\Users\rafal\anaconda3\lib\site-packages\notebook\notebookapp.py", line 80, in from .services.contents.manager import ContentsManager File "C:\Users\rafal\anaconda3\lib\site-packages\notebook\services\contents\manager.py", line 17, in from nbformat import sign, validate as validate_nb, ValidationError File "C:\Users\rafal\anaconda3\lib\site-packages\nbformat__init.py", line 32, in from .validator import validate, ValidationError File "C:\Users\rafal\anaconda3\lib\site-packages\nbformat\validator.py", line 12, in from .json_compat import get_current_validator, ValidationError File "C:\Users\rafal\anaconda3\lib\site-packages\nbformat\json_compat.py", line 10, in import jsonschema File "C:\Users\rafal\anaconda3\lib\site-packages\jsonschema\init.py", line 34, in version__ = metadata.version("jsonschema") AttributeError: module 'importlib_metadata' has no attribute 'version'
Could someone please help to resolve this issue?
