How can I use the deeplearning-mplstyle plt style? The use of lab of machine learning

Question

I'm going to try machine learing lab which is conducted by Prof.Andrew Ng in my pycharm.
but if I run one of it and found that it just run as follows:

import math,copy
import numpy as np
import matplotlib.pyplot as plt
plt.style.use('./deeplearning.mplstyle')

but if I attach this to the end

from lab_utils_uni import plt_house_x, plt_contour_wgrad, plt_divergence, plt_gradients

it shows the error

`Traceback (most recent call last):

    with open(fname, encoding=encoding) as f:

The above exception was the direct cause of the following exception:

OSError: 'linear_regression/deeplearning.mplstyle' not found in the style library and input is not a valid URL or path; see `style.available` for list of available styles

In addition the D:\pythonProject1\venv is my workspace.
I promise that util.py and mplstyle are in the directory.
It takes me about 3h and I still can't find solution. enter image description here enter image description here

And I had tried to attach the mplstyle to the path "D:\pythonProject1\venv\lib\site-packages\matplotlib\style".
It also can't effect.

Try this

plt.style.use('file:c://YOUR_ABSOLUTE_FILE_PATH/deeplearning.style')

BTW, my code editor is VS Code.
