Bug Description

There is an incompatability between GnuRadio 3.10 and the gr-limesdr package: when using the package, the following error is generated:
 in <module>
    import limesdr
  File "/usr/lib/python3/dist-packages/limesdr/__init__.py", line 18, in <module>
    from .limesdr_python import *
ImportError: generic_type: type "sink" referenced unknown base type "gr::block"

Some research suggests this may be caused by a different version of pybind being used to build the plug-in vs. the main GnuRadio package.

More information:
Editing /usr/lib/python3/dist-packages/limesdr/__init__.py and adding the following line
try:
    # this might fail if the module is python-only
+++ from gnuradio_base import *
    from .limesdr_python import *

Allows the code to get a bit further along - instead of the error above it gets this error:

  File "~/.grc_gnuradio/Receiver.py", line 241, in __init__
    self.limesdr_source_1 = limesdr.source('', 0, '')
AttributeError: module 'limesdr' has no attribute 'source'

This is in the code generated by Gnu Radio Companion for a flow diagram with the LimeSDR source in it.
