Hi Jon, It is until today that I realize I lost your email a long time ago. I hope you still remember. I was asking you about the memory problem. You are absolutely right. The "platform.architecture()" shows python is compiled in 32 bit. I wonder if this means I should build python and all related packages again.
Have a nice day!
