I am having trouble running my code. I never encountered this error before (a few months ago) when I wrote the code, I was even able to obtain my plot. However, when I tried running it again yesterday, I suddenly encountered errors (see below).

THIS IS MY CODE ` import importlib

import pandas as pd import numpy as np import scienceplots

import sys from pathlib import Path from scipy import signal

import matplotlib.pyplot as plt

import matplotlib.ticker as ticker import matplotlib.gridspec as gridspec`

THESE ARE THE ERRORS

I tried downgrading Python, uninstalling and reinstalling it, updating packages, etc. I also found suggestions stating that I need to use sudo install texlive-full. I attempted to install it, but the process took too long and eventually ended with an error.
