在完成Deeplearning.AI的机器学习专业化之后，我试图在概念和实验室上修改自己，我设法下载了所有文件并将它们存储在同一个文件夹中。这是问题的一个变体（plt.style.use('./deeplearning.mplstyle') is not working）。但我有一个不同的错误。

TypeError: the 'package' argument is required to perform a relative import for './deeplearning'

我试着运行这段代码

import numpy as np
import matplotlib.pyplot as plt
import tensorflow as tf
from tensorflow.keras.layers import Dense, Input
from tensorflow.keras import Sequential
from tensorflow.keras.losses import MeanSquaredError, BinaryCrossentropy
from tensorflow.keras.activations import sigmoid
from lab_utils_common import dlc

并得到了错误

从我所能理解的和我能解码的问题来看，似乎./deeplearning.mplstyle根本没有作为matplotlib的选项进行更新，不幸的是，更改为任何其他样式都会导致课程中其他文件也使用deeplearning. mplstyle产生更多错误。
我应该把包参数放在哪里来解决这个相对重要的问题？
