[SciPy-user] storing numpy arrays

[Michael Hearne]

I have a MySQL database, in which I would like to store a numpy array as 
a BLOB.  I'm trying to find out the easiest/most efficient way to 
store/extract this data.

I looked at scipy.io.write_array, which looked somewhat promising, until 
I saw the notice that this method is deprecated in favor of numpy.savetxt.

I could potentially use scipy.io.savemat/loadmat, but that would require 
writing to a binary (.mat file), then reading it back in again just to 
stuff it into the database.

I could also use pickle, but I found a bug report somewhere that pickle 
may do strange things to the array in the process or reading or writing.

Does anyone have any suggestions?

Thanks,

Mike
