Deprecation warning

[shingike]

Apparently, it was caused by adding a warning filtering:

import warnings
warnings.filterwarnings('error')

As soon as I removed them, the issue is resolved.

Hello @shingike
Sorry for the late reply. I just notice your issue.
Do you still have troubles? Should I take a look?

Add a switch (see here)

...
# store the dtype
if sys.version_info[0] < 3:
    dtype_sequence = collections.Sequence  # py2
else:
      dtype_sequence = collections.abc.Sequence  # py3.9
...
# use it
if (isinstance(inputs, dtype_sequence):
    ...

However, the six package is said to be more appropriate https://six.readthedocs.io/

something like six.moves.collections_abc
