Error converting MicroCluster to numpy array

[asieriko]

Hello,

MicroClusters are inhomogeneous structures (lists, integers, ...) so when converting them to numpy array it throws an error:

ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 2 dimensions. The detected shape was (100, 10) + inhomogeneous part.
(FedStream-main/fdstream.py", line 161, in convert_to_numpy)

In order to fix this the following has to be changed:
from:

np.asarray(MicroCluster)

to:

np.asarray(MicroCluster, dtype="object")

Maybe there is some change in the default behaviour in np.asarray

I've found 4 appearances in microcluster.py, and 4 in fdstream.py.

If you are interested I can send you a Pull request.

@asieriko Thank you for your effort in helping maintain the codebase. You are absolutely right; the issue is caused by changes in behavior in the current numpy versions of np.asarray. I have accepted the pull request. I truly appreciate your contribution to maintaining the codebase.
