Hi, Does anyone know how to get fromfile and tofile to work from a tempfile.TemporaryFile? Or if its not possible? I am getting this: >>> import tempfile >>> f = tempfile.TemporaryFile() >>> f <open file '<fdopen>', mode 'w+b' at 0x01EE1728> >>> a = numpy.arange(10) >>> a.tofile(f) Traceback (most recent call last): File "<input>", line 1, in ? IOError: first argument must be a string or open file
Works for me: In [16]: f = tempfile.TemporaryFile() In [17]: a = ones(10) In [18]: a.tofile(f) In [19]: f.seek(0) In [20]: b = fromfile(f) In [21]: b Out[21]: array([ 1., 1., 1., 1., 1., 1., 1., 1., 1., 1.]) In [22]: f.close() What version of numpy are you running? Chuck
