Yesterday I installed the mysql connector package, today I can't start python anymore. Anacona won't start nor directly Python 3.6. The Anaconda prompt delivered:

Does anyone have an idea how to make Python run again? Thanks in Advance

Thanks amphibient,
I had set this environment variable 'cause I couldn't make mysql package work on Spyder:
D:\Programme\Anaconda\pkgs\sqlalchemy-1.1.13-py36h5948d12_0\Lib\site-packages\sqlalchemy\dialects\mysql\types.py
(Now I see .py is obviously no folder ;))
This messed everything up. I removed it and installed the package with
conda install mysql-connector-python typed into conda path.
Now everything works.

I am creating a jupyter notebook programatically with Python. Using the nbformat library.
Once I create the file:
fname = f'{filename}.ipynb'
with open(fname, 'w') as notebook:
nbf.write(nb, notebook)
I open the file with Jupyter Lab and get the following error in the terminal console:

I have been researching a lot, but I don't get to find the error... some guidance on why this is happening?
PD: the only solution I've found so far is openinig the notebook with vscode and somehow, the notebook gets fixed.
It was actually a very newbie error. I had written the names of the folders with accented characters. Therefore, Jupyter Lab couldn't recognize correctly the files.
I'm trying to freeze with either cx_freeze or pyInstaller a TraitsUI program that makes use of Chaco, Traits, TraitsUI and to a lesser extent mayavi (could actually be taken out). I need this to run on mac, linux, ubuntu so am avoiding py2exe. I've intentionally uninstalled pyqt and pyside so that only the wx backend is available.
Using cx_freeze, I encountered and reported a bug, so pyInstaller seems to be getting me the furthest. It generated an .exe file, but when I run the file I get warnings and an error. To generate the .exe file I did:
pyinstaller --onefile --name=pameapp pamemain.py
pyinstaller pameapp.exe
Upon running, the warnings are:

traits.trait_errors.TraitError: Could not find any UI toolkit called 'null'
pyface probably has a lot of dynamic imports, so this must be a problem encountered by anyone who tries to freeze ETS. Is there a single fix to get this working?
Considering the older stuff floating around the web on success rates to freezing an ETS program, is it even worth further investment? To us, having people avoid configuring python for this application would be a huge plus.
Thanks.
Pyface.toolkit you are using is using dynamic import:
def import_toolkit(tk):
try:
# Try and import the toolkit's pyface backend init module.
be = 'pyface.ui.%s.' % tk
__import__(be + 'init')
except:
raise
return be
So pyinstaller is not able to detect this. Check with python -v b.py 2>&1 | grep imp what is the specific import and add hook file (hook-.py) with proper hiddenimports list.
However I've did some tests in local and I am not able to do working test schema with __import__. It's strange as I did some debugging and I found that hiddenimport is added but still not usable.
Problem using MySQLdb after installing MySQLdb-python. I followed the instructions I followed the instruction that had me delete the build and delete the egg then modify the my_config and then run the install again. I also tried installing the 64 bit version still no luck

what should i do ?
i need to use arcpy in eclipse also and i can't!
This sometimes happens when there are not enough licenses to go around, or if your organization has disabled automated library downloading as part of their software suite.
Check what version of Python you're using in Eclipse, I know friends who've had to download condas in order to import arcpy without fail.
I was giving a look at the "Learn Python The Hard Way" tutorial and when it told me to try it out by typing Python in Powershell after I installed it just kept giving me this:

I also tried running through the command prompt and got the same error. I've installed and uninstalled python about 3 times and have done a few reboots to no avail. I am very new to python and I'm confused on what to do here. I would also appreciate any links to other python tutorials.
In this case, from my understanding, you have no modules called "MAXREPEAT" or you(or the installer) have installed it somewhere wrong. A reinstallation or redirecting the path should get it to work.
