Hi Michael, Thanks for the reply. I'm using ptxdist-2023.10.0. Python is called by the node build system, and it looks like it was using the host python in my case. Possibly it's because another package selects host python; maybe it works if host python isn't there at all. I'm happy with the workaround, but I see your point of wanting to use system python instead. Is there any way to check/fix why it selects host python on my system?
