database not recognized

[SaniHarouna-Mayer]

Dear all,
I am trying to calculate x-ray attenuations but xraydb doesn't seam to recognize xraydb.sqlite as a valid database. Xraydb was installed via conda-forge, Python verision 3.8.12.

When executing e.g.:
import numpy as np import matplotlib.pyplot as plt from xraydb import mu_elam energy = np.arange(500, 120000, 10) elem = 'C' mu_total = mu_elam(elem, energy, kind='total')

I get following error:
Traceback (most recent call last): File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/pydevd.py", line 1448, in _exec pydev_imports.execfile(file, globals, locals) # execute the script File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/_pydev_imps/_pydev_execfile.py", line 18, in execfile exec(compile(contents+"\n", file, 'exec'), glob, loc) File "/Users/admin/Wolke/technical_paper/figures/data/plots.py", line 65, in <module> mu_total = mu_elam(elem, energy, kind='total') File "/Users/admin/anaconda3/envs/stanni/lib/python3.8/site-packages/xraydb/xray.py", line 309, in mu_elam xdb = get_xraydb() File "/Users/admin/anaconda3/envs/stanni/lib/python3.8/site-packages/xraydb/xray.py", line 157, in get_xraydb _xraydb = XrayDB() File "/Users/admin/anaconda3/envs/stanni/lib/python3.8/site-packages/xraydb/xraydb.py", line 84, in __init__ raise ValueError("'%s' is not a valid X-ray Database file!" % dbname) ValueError: '/Users/admin/anaconda3/envs/stanni/lib/python3.8/site-packages/xraydb/xraydb.sqlite' is not a valid X-ray Database file!

Everything seems to be properly downloaded and in place. Any idea how I could solve that issue?

Best,
Sani

@SaniHarouna-Mayer Sorry for the trouble (and delay - I was traveling).

I think this is probably the same as #24 and is probably fixed in the GitHub master branch.

I will try to push a release of 4.5.2 later today or tomorrow which should fix this.

@newville
After upgrading to 4.5.2 everything works flawlessly.
Many thanks!!
