Hi! I just updated to Anaconda3 2021.11 on Windows 10. Now I can switch in Anaconda Navigator between base (root) and Anaconda3, which presumably is the installation folder name I chose. When I choose base (root) I can launch Spyder 4.1.2 which is installed there. When I choose the newly installed Anaconda3, where I installed Spyder 5.1.5 I get following errors when trying to launch Spyder: Error processing line 1 of C:\Anaconda3\lib\site-packages\matplotlib-3.5.1-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Error processing line 1 of C:\Anaconda3\lib\site-packages\sphinxcontrib\_applehelp-1.0.2-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Error processing line 1 of C:\Anaconda3\lib\site-packages\sphinxcontrib\_devhelp-1.0.2-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Error processing line 1 of C:\Anaconda3\lib\site-packages\sphinxcontrib\_htmlhelp-2.0.0-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Error processing line 1 of C:\Anaconda3\lib\site-packages\sphinxcontrib\_jsmath-1.0.1-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Error processing line 1 of C:\Anaconda3\lib\site-packages\sphinxcontrib\_qthelp-1.0.3-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Error processing line 1 of C:\Anaconda3\lib\site-packages\sphinxcontrib\_serializinghtml-1.1.5-py3.9-nspkg.pth: Traceback (most recent call last): File “C:\Anaconda\Lib\site.py”, line 168, in addpackage exec(line) File “”, line 1, in File “C:\Anaconda\Lib\importlib\__init_\_.py”, line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Remainder of file ignored Traceback (most recent call last): File “C:\Anaconda\Lib\site-packages\zmq\__init_\_.py”, line 36, in _load\_libzmq from . import libzmq ImportError: cannot import name ‘libzmq’ from partially initialized module ‘zmq’ (most likely due to a circular import) (C:\Anaconda\Lib\site-packages\zmq\_init_.py) During handling of the above exception, another exception occurred: Traceback (most recent call last): File “C:\Anaconda3\Scripts\spyder-script.py”, line 6, in from spyder.app.start import main File “C:\Anaconda\Lib\site-packages\spyder\app\start.py”, line 22, in import zmq File “C:\Anaconda\Lib\site-packages\zmq\__init_\_.py”, line 61, in _load\_libzmq() File "C:\Anaconda\Lib\site-packages\zmq\_init_.py", line 39, in _load\_libzmq from importlib.util import find\_spec File "C:\Anaconda\Lib\importlib\_init_.py", line 51, in \_w\_long = \_bootstrap\_external.\_w\_long AttributeError: module ‘importlib.\_bootstrap\_external’ has no attribute ‘\_w\_long’ Can anyone please help me to resolve this?

You have 2 versions of Anaconda installed, this can be seen from your traceback: ```auto Error processing line 1 of C:\Anaconda3\lib\... ``` And: ```auto File “C:\Anaconda\Lib\site.py”, line 168, in ... ``` Whenever you have a traceback which shows multiple versions of Python are being used something is going badly wrong. I would strongly recommend uninstalling your Anacondas and install only one version of Anaconda ---
