为了了解深度学习和神经网络，我尝试使用conda 4.9.1（最初包含Python 3.8.3）在笔记本电脑（Dell Inspiron 5559、4GB RAM，Windows 10）上安装Tensorflow 。为此，我使用了以下命令：

conda create -n tf tensorflow

它成功运行并安装了Python 3.7.9，tensorflow 2.1.0还有许多其他模块。现在，我想测试它是否有效，因此在Python终端中，导入了一些模块。已成功导入math和numpy。但是当我导入tensorflow时，该过程失败，并显示以下内容：

>>> import tensorflow

ValueError: source code string cannot contain null bytes

即使我运行导入Tensorflow的程序，也会发生此错误。

我检查了其他大多数教程，似乎没有人遇到此错误。我还尝试使用较低版本的Python和Tensorflow，但发生相同的错误。

谁能找到正在发生的事情，我该怎么办？
