Unable to load ioneq #453

Closed nawinnova closed 1 year ago

nawinnova commented 1 year ago

Hi all,

I have just recently install ChiantiPy (version 0.15.1) and try to follow the quickguide. However, I am unable to load the ion equilibrium data due to some error.

Here is the code I am using.

`import os import ChiantiPy import ChiantiPy.core as ch import numpy as np import matplotlib.pyplot as plt import ChiantiPy.tools.data as chdata

os.environ['XUVTOP'] = '/Users/nawinngampoopun/Desktop/CHIANTI/CHIANTI_10.1_database/'

Ocharge = ch.ioneq(8) Ocharge.load() `

The return error is AttributeError: module 'ChiantiPy.tools.data' has no attribute 'Defaults'

Is there anyway to solve this issue?

Thank you, Nawin

I am looking into this

Try:

defaults=chio.defaultsRead()

and see what you get for the values of the dict 'defaults'

one should be

'ioneqfile': 'chianti',

Hi Ken,

Here is the values of dict

{'abundfile': 'sun_photospheric_2015_scott', 'ioneqfile': 'chianti', 'wavelength': 'angstrom', 'flux': 'energy', 'gui': True}

next thing to try:

import ChiantiPy.tools.data as chdata

then chdata.Defaults

should look like what you got with chio.defaultsRead()

so , theck that.

I receive an error this time, similar to the original problem.

import ChiantiPy.tools.data as chdata ----> chdata.Defaults

AttributeError: module 'ChiantiPy.tools.data' has no attribute 'Defaults'

Also, I can add that I am running this in VSCode on macOS, and install ChiantiPy using pip

kdere commented 1 year ago

I have never tried VSCode.

can you try this in a Python console, or a jupyter notebook?

does chdata have any attributes such as Xuvtop Ip MasterList ? Ken

Hi, I also try to run it using IPython

Here is some results

Hi Ken,

I have found the problem now. It maybe because I import the ChiantiPy before define os.environ['XUVTOP']. Now the code is working now after I swap the code and restart the kernel and

Thank you for your help! Nawin
