[proFit-list] problem with Python

Wed Feb 12 00:21:58 CST 2014

I have run into this problem myself (I like to use the Anaconda distribution).

In theory, you should be able to tell pro Fit your “Path to Python Library” in Preferences>Scripting. Then pro Fit should be able to import everything in that path’s "site-packages” folder. 

This works for some versions of Python but not for others. 

For example, the default value of "Path to Python Library" is: /Library/Frameworks/Python.framework/Versions/2.6/Python
Any package that you install there, you should be able to import into pro Fit. 

If you install the python.org's Python distribution for, say, 2.7, the Python Library path is now: /Library/Frameworks/Python.framework/Versions/2.7/Python. If you tell pro Fit to use it, it accepts it. 

This works with no issues. For example, I am able to import numpy. To test where the imported package file actually is, you can use Python’s construct __file__.

Example script:

## script test
import numpy as np
print np.__file__

On my system, this outputs: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/numpy/__init__.pyc
(Of course, for this to work you have to have numpy installed in the 2.7 hierarchy). 

However, things do not work for Anaconda. The pro Fit developers explained to me that this is because that version is 64 bits, while pro Fit is a 32 bit application. This has the undesirably side effect that I have to maintain two Python environments: my preferred Anaconda (with a lot of packages installed) and the “official” Python 2.x (or 3.x) for use with pro Fit. 

Hopefully in the future pro Fit will make the jump to 64 bits and will be able to accept the Anaconda version of Python and coexist happily. 

Now, just for fun, I tried installing pandas in my 2.7 installation. For this, I opened terminal and typed:

/Library/Frameworks/Python.framework/Versions/2.7/bin/pip install pandas
(remember, you want to run the pip inside the 2.7 hierarchy, not inside EPD)

After a lot of gibberish you should see: Successfully installed pandas python-dateutil putz six
(This means that pandas and its dependencies were installed). 

After that, I was able to use pandas in IDLE:
>>> import pandas as pd
>>> dates = pd.date_range('20140211',periods=6)
>>> dates
<class 'pandas.tseries.index.DatetimeIndex'>
[2014-02-11, ..., 2014-02-16]
Length: 6, Freq: D, Timezone: None

Tried the same thing in a pro Fit script and it worked. 

Hope this helps.
