在 Pycharm 中加载原生 TensorFlow 运行时失败

Question

这就是我目前在 PyCharm 项目中运行的内容

Windows 10
PyCharm 2020.1.1 (Community Edition)
Python 3.7.7
TensorFlow 2.2.0

这是我在导入方面的代码：

import math
import pandas_datareader as web
import numpy as np
import pandas as pd
from sklearn.preprocessing import MinMaxScaler
from keras.models import Sequential
from keras.layers import Dense, LSTM
import matplotlib.pyplot as plt
plt.style.use('fivethirtyeight')

这是错误......

Failed to load the native TensorFlow runtime.

我必须尝试卸载、重新安装、升级、从 Python 3.8 更改为 3.7，...，但我仍然收到错误。

这是版本问题。

我将 TensorFlow 改成 1.15，出现 cudart64_100 错误。

然后我安装了带有 cudart64_101.dll 的 CUDA 10.1 问题仍然存在。

然后我就关注了这个帖子....

下载，解压OP提供的cudart64_100.dll....

重新安装了 TensorFlow 2.0.0。 重新启动了我的电脑。 问题解决了。

仅适用于未来警告；但没什么大不了的。我现在可以运行我的程序了。
