Hi all,
I've got a fairly large (but not huge, 58mb) tab seperated text file, with
approximately 200 columns and 56k rows of numbers and strings.
Here's a snippet of my code to create a numpy matrix from the data file...
data = map(lambda x : x.strip().split('\t'), sys.stdin.readlines())
d
"If the text file has 'numbers and strings' how is numpy meant to know
what dtype to use?
Please try genfromtxt especially if columns contain both numbers and
strings."
Well, I suppose they are all considered to be strings here. I haven't tried
to convert the numbers to floats yet.
"What happens
the information. To fix my problem, I tried taking out the row
names (leaving only numerical information), and converting the 2D list to
floats. I still had the same problem.
