我已经安装了scanpy，当我检查pip show它时：

C:\Users\plain>pip show scanpy

但是当我尝试将其导入 Jupyter Notebook 时，我收到一条错误消息：

import scanpy as sc
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-3-0074c9bc0b31> in <module>
----> 1 import scanpy as sc

ModuleNotFoundError: No module named 'scanpy'

有人知道为什么吗？

谢谢你的帮助！

在这种情况下，我总是检查 Python 是否“看到”了我的环境。最简单的方法是打印 Pythonpath。在 jupyter notebook 中运行此代码以确保 Python 知道 scanpy 安装路径：

import sys
print(sys.path)

您的文件夹c:\users\plain\appdata\local\programs\python\python39\lib\site-packages应该在打印路径中
