Error importing pyhdf module in Python

Question

I have followed the instructions from http://hdfeos.org/software/pyhdf.php detailing how to install pyhdf and subsequently attempted to run the example code listed on this site (found here ). Unfortunately, when I run the example code (which I saved as hdf.py) I get the following error message:

$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)
ImportError: dlopen(/Users/kyleniezgoda/anaconda/lib/python2.7/site-packages/pyhdf-0.9.0-py2.7-macosx-10.5-x86_64.egg/pyhdf/_hdfext.so, 2): Library not loaded: libjpeg.8.dylib

  Reason: image not found

Anyone see something similar to this or have any suggestions? I am running on Mac OS 10.10.3 Yosemite, if that helps.

Answer 1

I solved the same problem by upgrading numpy version. You can type following words in Anaconda Prompt:

pip install numpy --upgrade

and then import it again.

Answer 2

在 Anaconda 提示符下使用以下命令安装 jpeg：

conda install -c conda-forge jpeg
