Anaconda/Conda on OS X 11 -- Broken Jupyter Notebook with DEFAULT installation

I am running the latest Anaconda on OS X 11 and cannot for the life of me figure out how to get jupyter notebook to run. It ends in this error:

I have tried fresh installs of both miniconda and anaconda without success. Nothing seems to work.
It baffles me that a default install of anaconda (no updates, no extra packages, nothing) is broken. Do these people even test their stuff?
Any solutions or suggestions? Thanks in advance!

Cannot import tensorflow in python3 and ImportError: This package should not be accessible on Python 3

I am trying to use tensorflow for research in my macbook. I use pip3 to install tensorflow in the system (not in virtual environment).
At first, I just want to verify tensorflow can be correctly imported via python3 in terminal. However, sometimes, I got the following problem when importing.
>>>import tensorflow as tf

Expected in: flat namespace in /Library/Python/2.7/site-packages/numpy/core/multiarray.so
This error could only be solved if I ran the following code firstly before python3 execution
unset PYTHONPATH
If I didn't unset PYTHONPATH, I also found errors when checking the version of pip3 using
pip3 --version
The errors are shown as follows.
>> pip3 --version

raise ImportError('This package should not be accessible on Python 3. '
ImportError: This package should not be accessible on Python 3. Either you are trying to run from the python-future src folder or your installation of python-future is corrupted.
I thought it was so inconvenient to unset PYTHONPATH every time, so is there any solutions for this problem? I also want to import tensorflow in other text editor, such as Sublime and Pycharm, so I was really not sure what to do next.

I tried the same scenario. It is working fine for me. In the first error it seems your python installation is messed up. If you are using python3 in terminal, it should not refer to 2.7 libraries.
Also I dont think you require unset PYTHONPATH everytime. First thing is you dont need to setup PYTHONPATH. It seems the installation got issue.
You using homebrew in mac to install packages. If not I will say use homebrew and it will work as charm. As it adds dependency properly.
Thanks,

import CommonMark
ModuleNotFoundError: No module named 'CommonMark'
Acutually I found these error on this web and tried to install the r-commonmark 1.4 but it does not work well now.
Please tell me how to deal with it.

CommonMark is a package that Orange used. It was renamed in the latest release what causes that imports do not work. The issue should be solved by installing newer Orange3 version3.16.0
