It seems that scikit-learn has not been built correctly.

When running RecBole on GPU by setting confit['device'] = 'cuda', I received the following errors:

Traceback (most recent call last):
File "/home/zf_qzh/Python3/lib/python3.8/site-packages/sklearn/__check_build/init.py", line 48, in
from ._check_build import check_build # noqa
ImportError: dlopen: cannot load any more object with static TLS

During handling of the above exception, another exception occurred:

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run python setup.py install or
make in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

How can I settle this case? Thanks~

@dyoflut Hello, thanks for your attention to RecBole!
This problem is probably due to the wrong order of importing package. You can reorder dependent packages. You can refer to this sklearn issue for specific solutions.

Thanks a lot! After putting 'import sklearn' before all other pkgs, the problem was perfectly settled.
