[ferret_users] Install and running pyferret problem

["Yu, Hao-Cheng" <danish.url@xxxxxxxxx>]

Hi, everyone

I got the following errors after install and running pyferret.

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/pyferret/lib/python2.6/site-packages/pyferret/__init__.py", line 50, in <module>
    from pyferret import datamethods
  File "/opt/pyferret/lib/python2.6/site-packages/pyferret/datamethods.py", line 9, in <module>
    import numpy
ImportError: No module named numpy

I download from https://github.com/NOAA-PMEL/PyFerret/releases/download/v7.1.0-final/pyferret-7.1.0-RHEL6-64.tar.gz

With python2.6 and CentOS 6.5 Env, as well as Finstall to configure.

I modify python_subdir="python2.7" to 2.6 from original ferret_path files
Follow this mail archive http://www.pmel.noaa.gov/maillists/tmap/ferret_users/fu_2014/msg00414.html

Both PYTHONPATH & LD_LIBRARY_PATH were set correctly.

Still have no clue how to fix it. 

Could anybody give me some hints?

Dan
