error using example code

Matminer
1

Hi,

I am trying to run the example on the webpage: https://hackingmaterials.github.io/matminer/…

from matminer.data_retrieval.retrieve_MP import MPDataRetrieval

api_key=‘something’ #blanking out my actual key

df_mp = MPDataRetrieval().get_dataframe(api_key,criteria=‘Si’, properties=[‘band_gap’])

and get error:


<details class='elided'>
<summary title='Show trimmed content'>&#183;&#183;&#183;</summary>

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-3-3e513d6b3462> in <module>()
----> 1 df_mp = MPDataRetrieval().get_dataframe(api_key,criteria='Si', properties=['band_gap'])

TypeError
: get_dataframe() got multiple values for argument 'criteria'
Any ideas?
Sincerely,
tom
