I have installed anaconda in mac os sierra. Simple python scripts run fine. However, when I try to run jupyter-notebook it fails.
The error message is following:

I checked the dylib file, but it is there. What's wrong here?
Bhishan:ls /usr/lib/libsqlite3.dylib
/usr/lib/libsqlite3.dylib*
Similar problems:
No module named _sqlite3
But they did not solve my problem.
Your problem is most likely due to several python envirionments.
Check this question.
Also this question maybe relevant.
Also try to see all installed packages with conda.
I have faced the same issue.
For me installing sqlite via brew solved the issue.
brew install sqlite

I am trying to run a python script using ASE library, I have installed ase (https://wiki.fysik.dtu.dk/ase/install.html)and run my python script using this library on my terminal. I have made a virtual env named 'MLC_env' and have already installed the ase library there.
There is a folder 'Desktop/MLC/MLC_env/lib/python3.10/site-packages/ase' which got installed over there. Now the the website (https://pypi.org/project/ase/) says Add ~/ase to your $PYTHONPATH environment variable and add ~/ase/bin to $PATH (assuming ~/ase is where your ASE folder is).
I am not able to figure out what exactly I have to do? How to add this ase folder to my pythonpath? Any suggestions will be helpful.
I tried to follow this answer Permanently add a directory to PYTHONPATH? , according to this I can try doing export PYTHONPATH="${PYTHONPATH}:/my/other/path"" where ~/ase will be the full path name of the ase folder. Shall I go ahead with this? any suggestions.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.10 from "/Users/anshumansinha/Desktop/MLC/MLC_env/bin/python3"
* The NumPy version is: "1.24.1"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Python version: Python 3.11.0
As Chris suspected the Python 3.11 is causing the issues I don't know why but I just downgraded to 3.8.10 and it resolved the issue.
when running "src/bitmessagemain.py" in the terminal it shows

from six import string_types
ImportError: No module named six
I am guessing it has to do something with the virtualenv due to bitmessage still running on python 2.7 but I cant figure it out. I've made the environment for bitmessage to run in and I keep getting the error.
You probably don't have the six Python module installed,
try this:
pip install six
I am having issues launching Jupyter Notebook. I have tried to do it two ways and seem to get errors.
1 - Launching from the Anaconda Prompt using the command jupyter notebook or directly choosing from the Anaconda menu
I get the following:

Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
2 - Launching from the command line with the same command
I get the following:

It seems like this is referring to a package called jsonschema which is not installed apparently, but running a pip install jsonschema does not solve the problem for me...
In the answer above I also have two two commands but they are a bit different
source /opt/anaconda/bin/activate root
and then
jupyter notebook
It seems like you have to go into your anaconda directory then bin, then you can
"activate root"
It also looks like you need to install some other dependencies for jupyter to run. Where is says
Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
So if the above doesn't work try installing the other dependency and try again
Based on this answer from a similar question, I managed to solve the problem by running these two commands:
conda update -n root conda
conda update --all
I thus updated all packages, and the notebook is now launching.
When I compile my python scripts I'm getting the following error message. This started happening when I installed Anaconda. I've tried to find a solution online to the problem but I've had no luck. Can anyone help with solving this?

Are you using virtualenv? When I ran into this issue it was because of some server update which messed with the python version being used by my virtualenv. I solved the problem by deleting the virtualenv and making a new identical one.
