Probably not the desired response. Can someone suggest a fix?
Thanks,

Hi Bruce,

Seems to be a typo in the Wiki. If you look at
http://wiki.tiker.net/PyCuda/Examples/MatrixTranspose (where
MatrixTranspose.py originally comes from), you can see in line 24 two
"#define"s in one line. Incidentally, if someone has an account there,
could you fix that?

Best regards,
Bogdan

Hi Bogdan,

Thanks for pointing that out. It seems that is not the only error in this
example. Adding a carriage return, and re-running yields a TypeError

Hi Bruce,

Looks like the docs for Function.prepare() are a bit outdated, I've created
a PR for that. As for the example, since I cannot register on the wiki
(some cryptic error appears), I've created a gist with the corrected
version: https://gist.github.com/Manticore/6ff4400cde2750e61bff

Fixes:
- Py3 safe
- Fixed indentation in run_benchmark()
- Fixed repetition of test sizes in run_benchmark()
- Added labels to the graphs and some description to the output

Best regards,
Bogdan

P.S. Fixes include corrected invocations of prepare() and prepared_call(),
of course.

Updated. For future reference--you can't sign up for user accounts, but
you *can* edit anonymously on that wiki.
