from exojax.spec import api
from exojax.utils.grids import wavenumber_grid
nus, wav, r = wavenumber_grid(24000.0, 26000.0, 1000, unit="AA", xsmode="premodit")
mdb = api.MdbHitemp("CO", nus, inherit_dataframe=True)

The code to load hitemp, for instance, the above code, ends up the following error.

Downloading 05_HITEMP2019.par.bz2 for CO (1/1).

The reason of the above error is not column=None but column=[], then it fails at here

if columns is not None:
    df = df[columns]

so, I modified it just as

if columns is not None and columns != []:
    df = df[columns]

in radis hitemp_load branch.

@ykawashima at least in my environment, a small correction of radis/api.hdf5.py solved the loading error. I pushed the correction at hitemp_load branch. Can you check it?

The sample code I used for checking:

from exojax.spec import api
from exojax.utils.grids import wavenumber_grid
nus, wav, r = wavenumber_grid(24000.0, 26000.0, 1000, unit="AA", xsmode="premodit")
mdb = api.MdbHitemp("CO", nus, inherit_dataframe=True)

@ykawashima Ah, sorry, this is a different error from one you reported. I couldn't reproduce you error... The below code works in my environement.

from exojax.spec import api
from exojax.utils.grids import wavenumber_grid
nus, wav, r = wavenumber_grid(24000.0, 26000.0, 1000, unit="AA", xsmode="premodit")
mdb = api.MdbHitran("CO", nus, nonair_broadening=True)
