Pynhd: GeoConnex NameError

[nluft2]

I'm using PythonWin with Python version 3.10 on a windows PC. I was trying out the quick start code for the pynhd package. Once I hit the code: gcx = GeoConnex("gages"). I get a NameError: name GeoConnex is not defined.

I expected my code to assign the value GeoConnex("gages") to the variable gcx.

import pynhd
gcx = GeoConnex("gages")

It seems that you forgot to import GeoConnecx. So instead of import pynhd you should have from pynhd import GeoConnex. Alternatively, you can directly use the geoconnex function instead of the GeoConnex class, like so:

import pynhd
gage = pynhd.geoconnex("gages", query={"provider_id": "01031500"})

I just tried it with gage = pynhd.geoconnex("gages", query={"provider_id": "01031500"}) and I still got a name error.

What's the output of pynhd.show_versions()?

apparently my python version has been reverted to my 3.7 version in this IDE so I will have to change that to python 3.10 but other than that, would any of these other things be an issue?

Since GeoConnex has been added to pynhd in the 0.13.1 version, you shouldn't have any issue using it. Can you please update your pynhd version to the latest (0.13.3) just to make sure you have this issue with the latest version as well. I just tested it with 0.13.3 and it works as expected.

[nluft2]

I can't seem to update the pynhd version.

[cheginit]

Right, the reason is that pynhd 0.13.2+ only supports Python 3.8+ since many of its dependencies (like xarray, pandas, and geopandas) have already dropped support for Python 3.7. So, first, you need to update your Python version to 3.8+ then you can update pynhd to the latest version.

[cheginit]

Did you still have this issue after the update?

[nluft2]

No, issue resolved. Thanks.
