Using CUDA in Ubuntu 11.10 -

starting development of cuda-based tools on ubuntu, , tried install/use sdk. however, devicequery gives

cuda driver version insufficient cuda runtime version

for reference:

# nvcc --version nvcc: nvidia (r) cuda compiler driver copyright (c) 2005-2011 nvidia corporation built on tue_oct_18_17:35:10_pdt_2011 cuda compilation tools, release 4.1, v0.2.1221 # cat /proc/driver/nvidia/version nvrm version: nvidia unix x86_64 kernel module 280.13 wed jul 27 16:53:56 pdt 2011 gcc version: gcc version 4.6.1 (ubuntu/linaro 4.6.1-9ubuntu3)

i obtain similar errors other tools (namely theano's gpu utilities).

the cuda runtime must match driver, i.e kernel module. seem have driver version 280.13 compatible 4.0 runtime. either downgrade runtime or upgrade driver/kernel module: dev driver 4.1 (285.05.32)

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
