map.reproject_to not finding optional package

[Matthew G Lennard]

Hi,

I'm trying to do some work with HMI observations and need to rotate some images.

When I follow the tutorial https://docs.sunpy.org/en/stable/generated/gallery/differential_rotation/reprojected_map.html

I am met with the following output:

'Traceback (most recent call last):

  File "/Users/matthew/miniconda3/envs/py3/lib/python3.11/site-packages/sunpy/map/mapbase.py", line 2716, in reproject_to
    import reproject
ModuleNotFoundError: No module named 'reproject'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Users/matthew/Documents/codes/rotation.py", line 28, in <module>
    out_warp = hmi_map.reproject_to(out_wcs)

    raise ImportError("This method requires the optional package `reproject`.") from exc
ImportError: This method requires the optional package `reproject`.'

Namely, Sunpy is not finding reproject.

When I run

'pip install reproject'

It says everything is installed correctly. But when I try importing reproject in Python, it is unable to find the package.

Has anyone had any similar issues and found a way to fix this?

Thanks :)

Hello,

If pip says that reproject is installed but python nor sunpy can find it, that would suggest that pip command is not the correct pip that should be within the the py3 environment that python and sunpy are in.

I would just open a new terminal, activate py3, then see if the pip command location is within that environment location.

DId you install sunpy via pip or conda?
