Hello, thank you for your answer. It looks like commenting that out worked. I wonder why that line wasn’t throwing an error when I used the v3.5 version, however. Is v4.0 more sensitive to this? And yes, the handle_close function closes the handle, similar to the “exit 0” command.

It looks like I didn’t install pip correctly, so after making sure I updated my environment variables and running

C:\Users\a623>python -m ensurepip

I was able to run the following:

C:\Users\a623>python -m pip install libpython

Then, I ran the test.q script, which weirdly gives me the same error as before:

I’m not sure why I’m getting the same error, because it looks like I have pip set up correctly and installed libpython, as you can see above.

When I try to reinstall libpython I get the error below:

Any idea what’s going on here?

Hello, I still haven’t been able to figure it out. Not sure if my team wants to continue using embedPy but if you figure it out let me know. I reached out to someone who works at kdb and they recommended taking a look at the FAQs link in the github: https://github.com/KxSystems/embedPy/blob/master/docs/faq.md. The first question/answer is related to the libpython error I’ve been getting and may help you. It looks like we need to enable python to allow shared libraries, which is not enabled if python is installed using the recommended method.

Thanks for your answer. Unfortunately I’m fairly new to kdb so I will need to take a look to find out more about this. I’ll let you know if I find the answers to your questions. Do you know if there’s anything I can read up on about this?
