cannot import name Transformer from pyproj

Question

I am trying to use Transformer from pyproj using the code below. I, however, get an error attached. What could be the issue?

aalways put full error message(startingat word "Traceback") in question (not comment) as text (not screenshot). There are other useful information. — furas, Dec 30 '20 at 08:13
error shows problem in module `noisedplanet` - maybe it expects some older version of `pyproj` and it tries to import `Transformer` but in `pyproj` I can see only [transformer.Transformer](https://github.com/pyproj4/pyproj/blob/master/pyproj/__init__.py#L65) — furas, Dec 30 '20 at 08:16
I see you already send [issues](https://github.com/arthurdjn/noiseplanet/issues/1) on noiseplanet :) At this moment you may only try to change `from pyproj import Transformer` into `from pyproj.transformer import Transformer` - but maybe code will need much more changes in imports — furas, Dec 30 '20 at 08:20
@furas Thank you, I have amended the question. Hope that's better. I have attempted to use ```from pyproj.transformer import Transformer``` it then throws off another ImportError ```cannot import name 'CRS' from pyproj ```. So I suppose this would require much more changes. Trying to roll back to a previous version of pyproj, though I cant seem to find the documentation fro previous versions. Thanks again ! — Zhuwaki, Dec 30 '20 at 08:48
@Zhuwaki, can you please close your issue if the answer below solved your issue ? Thanks. — jegertor, Jan 08 '21 at 13:41
