Hello Alex,
make sure that you have the MonetDB-python or MonetDB-python3 packages installed:
dnf install MonetDB-python or dnf install MonetDB-python3
Also you will need to notify the MonetDB server that you want to start with embedded python support. If you are starting the server using the MonetDB daemon, you need to set the relevant property for your database:
monetdb set embedpy=true <database> or monetdb set embedpy3=true <database>
If you are starting the server by hand, then
mserver5 --dbpath=/path/to/database --set embedded_py=2 or mserver5 --dbpath=/path/to/database --set embedded_py=3
Best regards, Panos.

Roberto I have all mentioned packages installed. I do not have any issues with R though. Centos based instance also works fine.
Thanks Alex

Alex, Do you have packages python3-devel python3-numpy (python2-devel python2-numpy for python 2) installed in your Fedora system? Yes, you can import what you like in the body of your function, as long as the package is installed in your system.

MonetDB was installed following https://www.monetdb.org/downloads/Fedora/ with additional SELinux. I tried random_integers function from documentation with both embedpy=true and embedpy3=true separately but getting the same type of error: SQL Error [22000]: TypeException:user.s10_0[9]:'pyapi3.eval' undefined in: X_10:bat[:int] := pyapi3.eval(0x559cb0440270:ptr, "{ \n return numpy.random.randint(low, high, size=(amount,))\n}\n;":str, X_7:int, X_8:int, X_9:int); Both py2 and py3 versions work fine on my computer. How do I properly point to a specific python version to be used by MonetDB? Are there any specific env variables that should be set prior to installation/db creation? I tried to define PYTHONPATH but it did not help. Aside question: Can additional modules be imported in function body for PYTHON type functions or does it only work with numpy?
