Segmentation fault 11 after call the init function from petsc4py v3.9.1

[Zhilong]

I am using python 2.7. I installed the petsc v3.9.1 and petsc4py v3.9.1 on my Mac OS High Sierra 10.13.5. After the installation, I try to run a simple test, which just call the inin function. My code is as follows:

import petsc4py as pet pet.init()

The result is that python reports the Segmentation fault: 11.

I have no idea what happens.

I have numpy v1.14.5, mpi4py v3.0.0 installed.

There might be one clue: during my installation of petsc4py, it prints out something as follows:

In file included from src/PETSc.c:4: src/petsc4py.PETSc.c: In function 'initPETSc': src/petsc4py.PETSc.c:270152:22: note: variable tracking size limit exceeded with -fvar-tracking-assignments, retrying without __Pyx_PyMODINIT_FUNC initPETSc(void) ^~~~~

can anyone give me any solutions or ideas?

I have struggled for it for 10 days.

I think that warning you get is not relevant. Are you using system Python (/usr/bin/python), or Homebrew Python, or Anaconda Python? Could you try with PETSc 3.9.3 and use petsc4py from the maint branch or the git repo?

I use Anaconda Python

Are you aware that the conda-forge channel has petsc and petsc4py packages ready to be used? However, they do not support complex numbers yet.
