导入错误：没有名为 scipy.sparse 的模块

Question

新手上路，请多包涵

我使用以下命令在 Ubuntu 上安装了 Scipy：

 sudo apt-get install python-scipy
pip install scipy

但是当运行导入时，我得到这个错误：

 ImportError: No module named scipy.sparse

我搜索并尝试了以下并重新安装了 Scipy：

 sudo apt-get purge python-scipy

但仍然有同样的错误。

更新：我没有在我的 python 文件中导入 scipy，只是导入了 keras。

这是错误消息：
