           Hello,
   
   I have the same issue with the pyproj library using Python>=3.9. 
   
   When I import pyproj first, I have the exact same issue with Pulsar.
   If I import pulsar first, I have a bug in pyproj when I try to do this for 
example:
   ```python
   import pulsar
   import pyproj
   
   pyproj.Transformer.from_crs('epsg:4326', 'epsg:3035')
   ```
   ```Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File "/usr/local/lib/python3.9/site-packages/pyproj/transformer.py", line 
600, in from_crs
       cstrencode(CRS.from_user_input(crs_from).srs),
     File "/usr/local/lib/python3.9/site-packages/pyproj/crs/crs.py", line 501, 
in from_user_input
       return cls(value, **kwargs)
     File "/usr/local/lib/python3.9/site-packages/pyproj/crs/crs.py", line 348, 
in __init__
       self._local.crs = _CRS(self.srs)
     File "pyproj/_crs.pyx", line 2352, in pyproj._crs._CRS.__init__
   pyproj.exceptions.CRSError: Invalid projection: epsg:4326: (Internal Proj 
Error: proj_create: cannot build geodeticCRS 4326: cannot build unit of measure 
9122: non double value)
   ```
   
   So there seems to be some kind of conflict between cpp libraries since 
pyproj is also a wrapper for the PROJ cpp library and python 3.9+
   I do not need to install any version of grpcio for this to happen though.
   
   Thank you for looking into this because we are stuck at python 3.8 for now...
