Geopack says it has no attribute called geogsm, igrf_geo, etc.

[RadLad2019]

Hi I'm having some problems using some of the functions in geopack, for example

import geopack as gp

xgsm, ygsm, zgsm = gp.geogsm(x,y,100,1) print(xgsm,ygsm,zgsm)

returns module 'geopack' has no attribute 'geogsm' as well as other functions such as igrf_geo similarly saying that geopack doesn't have an attribute I used python3 -m pip install geopack to install it, is there anything else I need to install for geopack to work.

thanks in advance.

Hi there,

I've checked your code. There are several suggestions:

1. goepack depends on scipy and numpy. Please make sure they are installed.
2. Please try the following codes, which runs for me in python 3.7.3 on Mac:

Python 3.7.3 (default, Mar 27 2019, 09:23:15)

[Clang 10.0.1 (clang-1001.0.46.3)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

import geopack.geopack as gp

Load IGRF coefficients ...

ps = gp.recalc(100)

xgsm,ygsm,zgsm = gp.geogsm(2,1,100, 1)

xgsm,ygsm,zgsm

(-41.00700906453125, -19.962123759781406, 89.0221254665413)

Notice the differences between the above codes and your original codes. Remember to do recalc before any calculation. And remember to do geopack.geopack (this is a bit confusing due to the way the package is implemented).

Let me know if the problem persists.

Thanks, Sheng
