About Some ClusterData & ClusterLoader Issues!

[zhangchao162]

Hello,
When I use the ClusterData to partition a large graph, unfortunately I can not got the expected output "Computing METIS partitioning..." "Done!"

I got this error in Pycharm,
"Computing METIS partitioning...
free(): invalid size
free(): invalid size
python: malloc.c:3089: __libc_malloc: Assertion `!victim || chunk_is_mmapped (mem2chunk (victim)) || ar_ptr == arena_for_chunk (mem2chunk (victim))' failed."

sometimes, I got this error,
"Computing METIS partitioning...
munmap_chunk(): invalid pointer
munmap_chunk(): invalid pointer"

and even,
"Computing METIS partitioning...
double free or corruption (!prev)"
Pycharm can not stop run...

Who can tell me, what should I do?

[My Environment]
Ubuntu 18.04
python 3.8.12
pytorch 1.10.0
torch-geomtric 2.0.2
torch-sparse 0.6.12
