Hi guys, i was wunning a code and I installed a library and suddenly Jupyter stopped working. I uninstalled and installed twice but nothing, the message that appears said:
Traceback (most recent call last):

from markupsafe import soft_unicode
ImportError: cannot import name ‘soft_unicode’ from ‘markupsafe’ (C:\Users\acuad\AppData\Roaming\Python\Python39\site-packages\markupsafe_init_.py)
What can i do? 
Do you remember what library you installed? By looking at paths in the traceback, it seems that you may have two conflicting installations of markupsafe: one in Anaconda3 environment, and one in AppData\Roaming. It could be a result of mixing up conda install and pip install. Could you please:
- provide
conda list and pip list
2 . try running pip uninstall markupsafe and checking if Jupyter now works?
Note: also seen in Jupyter Notebook Launch Error
Hi I have the same problem and I have already tried downgrading Markupsafe and uninstalling it but I still get the same import error when I try to launch Jupyter Notebook from Anaconda.
Here is my code in terminal:
jupyter notebook
Traceback (most recent call last):

from markupsafe import soft_unicode
ImportError: cannot import name ‘soft_unicode’ from ‘markupsafe’ (/Users/name/.local/lib/python3.9/site-packages/markupsafe/init.py)
Would you mind providing conda list, pip list and jupyter --version output, please?

My conda list nor my pip list have markup safe.
This is my jupyter version output:
Selected Jupyter core packages…
IPython : 8.5.0
ipykernel : 6.16.0
ipywidgets : 8.0.2
jupyter_client : 7.3.5
jupyter_core : 5.0.0rc1
jupyter_server : not installed
jupyterlab : not installed

nbconvert : not installed
nbformat : not installed

qtconsole : not installed
traitlets : 5.4.0
Here discusses how the issue is coming up now because soft_unicode was removed from markupsafe. Covered here is the change where soft_unicode became soft_str.
Some of the more thorough options towards the bottom of that thread, such as here may help those encountering this issue at present.
This post has a nice command to force the re-install step if you are having issues.
(I’ll note that installing pycaret seems to lead to this issue, too. See here and here.)
