Hi Lisandro, Yes, that is the case, I ended up installing following your instructions since it was the simplest way to do it. I was actually trying to install PETSc 3.11 and then to install petsc4py using pip and providing environmental variables for PETSC_DIR and PETSC_ARCH, but I couldn’t make it work. Later Lisandro pointed out I could not use Python 3.8 for this.

Since you are in Python, I suspect the former. Can you build PETSc from scratch and try this? Does it work in serial? Can you send a small code that reproduces this? Well, I think Alejandro installed PETSc/petsc4py via pip as per my instructions. Can you confirm, Alejandro? -- Lisandro Dalcin ============ Research Scientist Extreme Computing Research Center (ECRC) King Abdullah University of Science and Technology (KAUST) http://ecrc.kaust.edu.sa/<https://urldefense.proofpoint.com/v2/url?u=http-3A__ecrc.kaust.edu.sa_&d=DwMFaQ&c=XYzUhXBD2cD-CornpT4QE19xOJBbRy-TBPLK0X9U2o8&r=U1Pry6bTDByPujjSnTcPY6KNXqrym6APfmtom-lIPFA&m=PWvcuQOFNDRTToOkEIL6eGXAKcbV_DG6KvK0ZhwMt24&s=VxgF-QiIr7bHGu42LRzRIPR5_WoGLSSDQdfhHp4qOSg&e=>
