PETScVector 无法导入

问题描述

我正在尝试在 OpenMDAO 中使用 MPI。我收到以下错误。它似乎来自this。但我不明白是什么导致了这个错误或如何解决它。

mpirun detected that one or more processes exited with non-zero status,thus causing
the job to be terminated. The first process to do so was:

我验证了 MPI 和 petsc 在我的环境中工作，我运行了给定 here 的小 petsc4py 脚本。它运行成功并给出了预期的结果。

为了完整起见，我正在使用 AMIEGO 运行 MINLP 优化，我的作业脚本如下。

#SBATCH -N 1
#SBATCH --ntasks-per-node=4
#SBATCH -c 1
#SBATCH -p batch
#SBATCH -C skylake

print_error_and_exit() { echo "***ERROR*** $*"; exit 1; }
module purge || print_error_and_exit "No 'module' command"
module load lang/Anaconda3/2020.02
module load mpI/OpenMPI/3.1.4-GCC-8.3.0

conda activate my-fastenv

mpirun -n $SLURM_NTASKS python /RBMDO/Power_Subsystem.py

是否知道可能导致此错误的原因？
