Hey Dave,
I have only tested it with Python 2.7, but I see no reason why it won't work with Python 2.6.
Regards,
Mark

Mark,
Can I use Python 2.6, or does it have to be 2.7?
Dave

Hey Dave,
In the 'default' branch only Python 2.7 UDFs are supported, Python 3 UDFs are currently in the works so you can choose which version you want to use. If you want to use Python 3 UDFs right now you can use the 'python3udf' branch instead.
Regards,
Mark

I just read your Embedded Python/NumPy blog post. Excellent!
Is there a preferred/required version of Python? I was looking at the config log and I see it checking for Python2 & Python3.

Mark,
Thanks for the info. To confirm, If I write my UDFs in Python, they will be executed in parallel (if required)?
Thanks, Dave

Hey Dave,
There's only a single R interpreter running. When an R function is called a lock is acquired that prevents other R functions from running at the same time. There has been some work to running multiple interpreters in parallel in separate processes for Python UDFs, but this has not been ported to R UDFs yet.
Regards,
Mark

All,
Quick question, how many R interpreters are running within MonetDB if you are using R UDFs? Is there a single shared interpreter or are there multiple copies running?
Thanks, Dave
