在Python中导入pyhdf模块时出错

Question

我遵循了http://hdfeos.org/software/pyhdf.php中详细说明如何安装pyhdf的说明，随后尝试运行此站点(找到here)上列出的示例代码。不幸的是，当我运行示例代码(我将其保存为hdf.py)时，我收到以下错误消息：

$python hdf.py
Traceback (most recent call last):
  File "hdf.py", line 28, in <module>
    from pyhdf.SD import SD, SDC
  File "/Users/kyleniezgoda/anaconda/lib/python2.7/site-packages/pyhdf-0.9.0-py2.7-macosx-10.5-x86_64.egg/pyhdf/SD.py", line 1004, in <module>

  _mod = imp.load_module('_hdfext', fp, pathname, description)

有没有人看到类似的东西，或者有什么建议？我在MacOS10.10.3Yosemite上运行，如果这有帮助的话。

Answer 1

我通过升级numpy版本解决了同样的问题。您可以在Anaconda提示符中键入以下单词：

pip install numpy --upgrade

然后再次导入。

Answer 2

在Anaconda提示符下使用以下命令安装jpeg：

conda install -c conda-forge jpeg
