[Numpy-discussion] tofile problems
Wed Jul 28 22:50:15 CDT 2010
I'm trying to write numpy arrays as binary data, to support a legacy
file format. So I open a file and write to it:
fp = open('somefile','w')
oldpos = fp.tell()
newpos = fp.tell()
diff = newpos - oldpos - somenumpyarray.nbytes
if diff != 0:
print 'ahhah! mismatch=',diff
I'm observing that every once in while I get 'ahhah! mismatch=1', that
is, the file position is advanced by one more byte than x.nbytes would give.
I'm using 1.4.1 on windows, python 2.5.
