`Camelot` gives error for not having the correct arm64 architecture of Ghostscript

I'm trying to use the python package camelot but get the following error, which I understand relates to my M1 mac I'm using:

>>> import camelot
>>> import pandas
>>> data = camelot.read_pdf('path/to/pdf.pdf')

I think this is same issue as this prior question, but the sole response to that question does not help as I already have the arm64 Python installed.

Steps taken:

brew install ghostscript
Checking that Ghostscript is installed as per the package documentation confirms that it is installed
Same issue occurs whether in a virtual environment not

Is this even possible to fix?

Solution

The comment from Siguza correctly pointed to the issue being with brew. Here's how I fixed the problem if anyone else finds themselves in similar situation:

Ran brew config in to confirm I was using x86_64 brew
Install brew from the .pkg file found here (I forgot to check if the arm64 brew was already installed or not though I do not think so)
Set arm64 brew as default: eval "$(/opt/homebrew/bin/brew shellenv)" - source

Create a link where camelot looks for Ghostscript as explained here

mkdir -p ~/lib
ln -s "$(brew --prefix gs)/lib/libgs.dylib" ~/lib
