[Numpy-discussion] PyObject arrays, pickling, tofile

[Tom D. <tom...@al...>]

It seems from my cursory look that numpy doesn't support the pickling
or the tofile of PyObject arrays.  I was wondering whether such
functionlity is in the pipeline or if there is little interest.
Personally, I would really like to see the feature in numpy but don't
know if I am up to implementing it myself.

Yes, you can pickle PyObject arrays, that is supposed to work.  What is 
not working? 

You can't use tofile on PyObject arrays, because I didn't have clear 
idea what to do.  Use Pickle for PyObject arrays.

Travis,

Thanks for your help.  Sorry for taking so long to get back to you.  I
wasn't on email for a few days.

I seem to be able to pickle and restore PyObject arrays but then
concatenates and takes give me the following error:

TypeError: fields with object members not yet supported.

What is even stranger is my stack trace stops at the call to numpy in
my code and doesn't show where it is failing in the numpy code.

The same operation on the numpy array that hasn't been pickled and
loaded back, works fine.
