High memory allocation for 14 MPIDs

Hi,

I have applied 39 different Matminer featurizers to a dataset consisting of 25126 entries from Materials Project (bandage > 0.1 and ICSD-entry base query). During this process, I found a high memory allocation for the following MPIDs:

“mp-1204629” #P16H216C80N32Cl8 #DOI: -

It is unknown to me what the cause of the problem is, but since I am running out of memory with 16GB available and doing featurization of one entry at the time, I believe that there is either a memory leak or a bug in the pymatgen structure object.

Best regards,
Oliver

Which featurizers are causing it?
