athenaCL at control rate in CSound ex1 - python error

[Jeffrey Trevino]

Thanks for answering my question about tpmap - I guess there can't be spaces, because the arguments in a command line argument vector are separated by spaces, and the parameter object and its arguments must be one argument in the argument vector? Is that why?

I'm starting to work through the examples in your paper about using athenaCL parameter objects at the control rate in CSound. I understand the first example, but I can't render it, because I'm getting a python error - maybe you've seen this before?:

I'm pretty sure that the code is right - I just copied it from the example in your paper:

It means - as i just found out - that PYTHONPATH is not set correctly to where AthenaCL is.
You should tell the Python the location of AthenaCL.
