Issue when using a new CRS : Problem with the synchronization with the latest version of EPSG database

[mabkoz]

Hello community!

I am writing a python script to convert coordinates from EPSG:4937 to EPSG:9895. I am facing an error which is that the EPSG:9895 is not a valid CRS " Invalid projection: EPSG:9895 (Internal Proj Error: proj_create: crs not found). " . When I go to https://epsg.org/ , I can find the CRS in the EPSG Dataset : v10.058. Correct if I am wrong but I think that the pyproj does not take into consideration the latest version of the Dataset which is v10.058.

trans_group = TransformerGroup(CRS("EPSG:4937").to_3d(),CRS("EPSG:9895").to_3d())

Could you please tell me how to force pyProj to synchronize with the latest version of EPSG Dataset in order to recognize my CRS ? Thank you in advance!

Expected Output

I expect the code to convert the coordinates from EPSG:4937 to EPSG:9895

## compute transformation
# LUREF2020 Bursa is computing 3D information (input N,E,U / lat, long, h)
print(trans_group.transformers[0].transform(49.54779150, 6.323181283, 217.401))

The result is supposed to be : (68133.95971970388, 91221.13528438336, 169.58002639748156) , but I encounter the error.

you can't. You'll need to use PROJ 9.0.1 that has the updated database when it is released, or build from master / 9.0 branch in the mean time. and possibly just replace the old proj.db with the updated one. But I can't recall if a proj.db from 9.x can work with PROJ 8.0. You may need to update to a pyproj version that supports PROJ 9.0 first.

To use pyproj with a different version of PROJ, this guide should come in handy: https://pyproj4.github.io/pyproj/stable/installation.html#installing-from-source
