The problem is in your external data file, I guess.

What happens, is that org creates a temporary tex file in a temporary
directory (it is in /tmp/babel-sth under Linux) and compiles this tex
file there.  At that directory your sin_py2csv.csv is not present.

So, one quick remedy should be to use an absolute path to the csv.

Regards,
Andreas
