Question

我尝试在Mac OSX上安装h5py并使用它的群组和数据集功能，但我遇到了问题。在其安装网页上，它表示初学者在Mac上使用它的最简单方法是安装Anaconda，这是我所做的，因为我仍然认为自己是一个没有经验的程序员。无论如何，在安装Anaconda并在iPython Notebook中输入以下脚本后，我得到一个＆＃34;未找到图像错误。＆＃34;

import h5py
import numpy as np
f = h5py.File("mytestfile.hdf5" , "w")

这是完整的错误（非常长）：

你的追溯表明你使用的是Canopy的Python，而不是Anaconda的。要么（1）确保Anaconda出现在Canopy之前的系统路径中，要么（2）使用Canopy的包管理器来安装h5py。由于您已经安装了Canopy，并且已经在您的路径中首先出现，这可能是您最简单的选择。您可以使用图形包管理器（可从欢迎屏幕访问）或从命令行安装h5py

enpkg h5py

安装后的h5py错误
