PyVISA Error: Insufficient system resources to perform necessary memory allocation

I am using PyVISA to communicate/control a Santec TSL-550 tunable laser via GPIB-USB.

My setup was working a few days ago and everything is correctly installed (NI-VISA, NI-MAX, NI 488.2, pip installed pyvisa-py, etc.), but I received this error randomly today.

The error in the terminal and in PyCharm is the same:

pyvisa.errors.VisaIOError: VI_ERROR_ALLOC (-1073807300): Insufficient system resources to perform necessary memory allocation

There are little resources online and no solution was found on the NI forum.

Solution

  • The solution was simple, but obscure.

    The GPIB side of the GPIB-USB adapter was not connected in all the way. I tightened it and the error was resolved.
