The following works fine with a python 2.4.3 installation, but with 2.5.1 I get:
In [1]:import numpy
In [2]:fid = file( '/tmp/tfile', 'w' )
In [3]:fid.write( numpy.zeros( 55 ).data ) --------------------------------------------------------------------------- <type 'exceptions.TypeError'> Traceback (most recent call last)
/home/gmabey/src/R9619_dev_acqlibweb/Projects/R9619_NChannelDetection/NED/<ipython console> in <module>()
<type 'exceptions.TypeError'>: non-character (or 8-bit) array cannot be interpreted as character buffer
<ipython console>(1)<module>()
I haven't tried it with python 2.5

Oh, and I'm using numpy from svn, updated this morning.

Does
In [1]: numpy.zeros(55).tofile('/tmp/tfile')
work?

Yes! I was unaware of that method. Are the two equivalent?
Also, I have identical results with python 2.5. I'm on AMD64-Linux, by the way.
Thanks, Glen
