1 year ago I ran that script on the development version of PDSim, no errors, ran fine.

11 months ago Its all solved now, there was a problem with my conda version! 👍
Hello pdsim community,
I installed all required packages (with the required versions, because newer cpython version have problems with declaring variables with cpdef instead of cdef) and run setup.py sucessfully. The GUI works also fine, but when I want to solve a simulation, then this error appears:
