Getting python chucks to run for the first time -- Error: (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e)))

Description

I am looking forward to starting to use the python chunks in quarto but I'm having trouble with this error message: (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e))).

I copied and tried to run the sample code from https://quarto.org/docs/computations/python.html but I get:

reticulate::repl_python()
Error: /Users/kellyanngarvey/opt/anaconda3/lib/libpython3.9.dylib - dlopen(/Users/kellyanngarvey/opt/anaconda3/lib/libpython3.9.dylib, 0x000A): tried: '/Users/kellyanngarvey/opt/anaconda3/lib/libpython3.9.dylib' (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e)))

I have anaconda installed and I just upated it. My version of R is also up to date.

I greatly appreciate any help on this!
Thanks so much,
Kelly

It seems you have a conflict of platform architecture, namely arm64 versus x86-84 probably resulting from installing the wrong tools.

What's your operating system and platform?
Did you install the proper tools in the same architecture as your operating system?

From the message, I am guessing you have macOS with an Apple Silicon chip which is arm64 and somehow your anaconda environment is using x86-64 while it should be arm64.

I'm on a Mac Air version 12.6.

I installed re intalled the anaconda with the arm64. I didn't realize there were two types of Mac downloads.

I re ran the code chunks and now it is having trouble reading in the packages: >>> import numpy as np
Traceback (most recent call last):

You have to install the modules used in the code.
This step is (or should be) described in the documentation next to the example.

pip3 install jupyter numpy matplotlib

Or

python3 -m pip install jupyter numpy matplotlib

Note that these commands need to be executed in your activated Conda environment.

Great! This worked, I can run the chunk.

For any other packages I have to install, can I use "pip3 install jupyter [package name here]"? Is that the correct way to think about this?

Thank you SO MUCH for your quick response and help!!

jupyter is already a module/library, see https://quarto.org/docs/computations/python.html#installation.
