hoomd installation with both mpi and gpu enabled

[yliu6677]

Hello I installed hoomd 4.7 with both mpi and gpu enabled. But when I type python in terminal and then import hoomd, it says

[yliu-XPS-8960:324458] shmem: mmap: an error occurred while determining whether or not /tmp/ompi.yliu-XPS-8960.1000/jf.0/2002780160/shared_mem_cuda_pool.yliu-XPS-8960 could be created.
[yliu-XPS-8960:324458] create_and_attach: unable to create shared memory BTL coordinating structure :: size 134217728 

This issue can be avoided by running import hoomd in jupyter notebook and create the file manually though... The number in the file is different if I type import hoomd in jupyter notebook or in terminal. So it is just a temporary relief of the problem if I stay in the same jupyter notebook and continue everything. Then it's not a solution to the problem...

This is a problem with MPI, not HOOMD. Search for "unable to create shared memory BTL coordinating structure" to find numerous discussions about this problem.

there are a lot of discussions on this and I didnt really understand how to solve that or if this is an issue that will affect the running somehow... Since I can successfully run tutorials Ill just leave this issue in future when it becomes critical.
