You can just catch the exception and decide what to do with it:
try:
data = np.loadtxt('foo.txt')
except IOError:
data = 0 # Or something similarNadav -----Original Message----- From: [email protected] on behalf of Maria Liukis Sent: Tue 25-May-10 01:14 To: [email protected] Subject: [Numpy-discussion] loadtxt raises an exception on empty file Hello everybody, I'm using numpy V1.3.0 and ran into a case when numpy.loadtxt('foo.txt') raised an exception: >>>import numpy as np >>>np.loadtxt('foo.txt') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/numpy/lib/io.py", line 456, in loadtxt raise IOError('End-of-file reached before encountering data.') IOError: End-of-file reached before encountering data. >>> if provided file 'foo.txt' is empty. Would anybody happen to know if it's a feature or a bug? I would expect it to return an empty array. numpy.fromfile() handles empty text files: >>> np.fromfile('foo.txt', sep='\t\n ') array([], dtype=float64) >>> Would anybody suggest a graceful way of handling empty files with numpy.loadtxt() (except for catching an IOError exception)?
