can't use dtale.__version__ to check current version after import in python

[injuryholmes]

Hi all, apologize if this question seems silly.
I found that dtale can't use dtale.version to check the current using version.

I found it relate to missing __verison__ attribute in __init__ file under dtale package.
But there is also a version parameter in setup.py, so it won't be a clever idea to keep the same value in two different locations.

I've checked pandas how they keep the version in __init__.py, and they've written a complex function;
https://github.com/pandas-dev/pandas/blob/3cb70a5f0d1dc386f7806fca75abff6f098b1539/pandas/_version.py#L1

Is there any good and simple way to fix this?

As a workaround until I update __version__ you can do the following:

import dtale.cli.clickutils as dtale_clickutils

print(dtale_clickutils.retrieve_meta_info_and_version("dtale")[1])
