Still actual: Cannot import name '_explicitize_args' from 'dash.development.base_component'

Hi, I am having problems running Dash DataTable scripts (example: take first one here: https://dash.plot.ly/datatable)

I am running following versions:
dash.version
‘1.5.1’

dash_table.version
‘4.5.0’

Error messages:

from dash.development.base_component import Component, _explicitize_args

ImportError: cannot import name ‘_explicitize_args’ from ‘dash.development.base_component’ (C:\Users\aem\AppData\Local\Continuum\anaconda3\envs\dash\lib\site-packages\dash\development\base_component.py)

Looking in DataTable.py at the top it says:
from dash.development.base_component import Component, _explicitize_args

I checked: importing ‘Component’ in prompt window works fine, importing ‘_explicitize_args’ definitely doesn’t

Any idea what the solution is? (a bit annoying since these are the latest versions…)
