![无法安装 h5py](https://linux22.com/image/906969/%E6%97%A0%E6%B3%95%E5%AE%89%E8%A3%85%20h5py.png)
我有 Ubuntu 16.04.5 并尝试安装 Keras。我需要 h5py 来实现这一点,但是安装时遇到了问题。当我输入:
sudo pip install h5py
我懂了:

我尝试过清除缓存、升级 pip 或使用 --no-cache-dir。但都无济于事。我该怎么办?

可以使用以下命令从 Ubuntu 18.04 及更早版本中的默认存储库安装适用于 Python 2.x 的 h5py:
sudo apt install python-h5py
可以使用以下命令从所有当前支持的 Ubuntu 版本中的默认存储库安装适用于 Python 3.x 的 h5py:
sudo apt install python3-h5py
