为什么no module named numpy

"no module named numpy" 错误通常意味着你的Python环境中没有安装NumPy库。你需要在命令行中使用pip安装NumPy库，如下所示：

pip install numpy

如果你已经安装了NumPy库，但仍然遇到此错误，请确保你的Python环境中正确安装了NumPy库。你可以通过在Python shell中输入以下命令来检查：

import numpy
print(numpy.__version__)

如果你的Python环境中没有正确安装NumPy库，请再次使用pip安装。如果你在使用虚拟环境，请确保你激活了正确的虚拟环境。
