ValueError: too many values to unpack (expected 3)

[GlewlwydGafaelf]

issue within riip

when entering line:
"ri = riip.RiiDataFrame()"

there is a warning produced "FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead."

and an error:
<<
"line 287, in _extract_raw_data
wls_n, ns, ks = np.array("
ValueError: too many values to unpack (expected 3). >>

is this new to this release?

Thank you for letting me know the issue.
I couldn't reproduce the issue with the recent released version 0.6.14 that was cleanly installed in a new conda environment.
If you use older version, please update it.
Then, please try to recreate the catalog and the database in the following steps:

1. In the folder where riip is installed, e.g. ~/anaconda3/lib/python3.9/site-packages/riip,
   there should be a folder and three files named "refractiveindex.info-database",
   "catalog.csv", "grid_data.csv", and "raw_data.csv". Please remove these folder and files.
2. Plsease try again "ri = riip.RiiDataFrame()".

The error occurred with clean install. I tried reducing the version to 0.6.13, 0.6.12, etc. The error is produced each time. I added a Try/except in the code - seems to fix the database but I was unable to get the example cylindrical waveguides to plot. Unsure as to why. Get Outlook for Android<https://aka.ms/AAb9ysg>

I tried another clean install on a different machine. Same issue as before. It looks like RIIP is the issue. Does it need Cython?

Please check your riip version by

import riip
riip.version

I guess that it will show '0.6.5'.
Nowadays, I cannot maintain riip and pymwm packages for windows,
and the version of riip stops at 0.6.5.
Please try to install linux version on WSL.

[GlewlwydGafaelf]

I have WSL installation. My version on windows was 0.4. I also tried installing on Google collab. Their virtual linux machine installed latest versions, and had same errors. Get Outlook for Android<https://aka.ms/AAb9ysg>
