Import Error: cannot import 'mdss_bias_scan' from 'aif360.sklearn.metrics'

Question

I would like to use the mdss_bias_scan function of aif360 for detecting the combination of variables that make up the privileged group and the non-privileged group.

When I try to import the function: from aif360.sklearn.metrics import mdss_bias_scan

I get the following error: Import error: cannot import 'mdss_bias_scan' from 'aif360.sklearn.metrics'.

Can you help me to fix it?

Update

The function mdss_bias_scan is not available in the version of aif360 you're using (v0.4.0).

Here's the source code of the file metrics.py at tag v0.4.0.

The function mdss_bias_scan was added via this commit which has not yet been released.

From the GitHub Source, it seems that you should import it as:

from aif360.sklearn.metrics.metrics import mdss_bias_scan

Also, make sure you have aif360 package installed in your Python environment. If not, install it using:

pip install aif360

Thanks, I Have already installed aif360 package – Amanda Feb 09 '22 at 09:48
@Amanda Did that solve the problem? – theoctober19th Feb 09 '22 at 09:50
No, I have encountered the same error. When I try to import other functions from the same library, I haven't the same error message. So, could the problem is with mdss_bias_scan? – Amanda Feb 09 '22 at 10:25
@Amanda Could you mention the version of `aif360` that's currently installed? It can be viewed with `pip show aif360` command. – theoctober19th Feb 09 '22 at 10:34
The version installed is 0.4.0 It should be the leatest one – Amanda Feb 09 '22 at 10:40
That explains it. `mdss_bias_scan` is not available in `metrics` in their `v0.4.0` release. I'll updated my answer accordingly. – theoctober19th Feb 09 '22 at 10:44
