Tutorial 3 Step 1 - Error using the Graph.describe() method

[skye0402]

I'm at step 1 of the tutorial: https://developers.sap.com/tutorials/hana-cloud-python-analysis-multimodel-3.html

Error I get is:

TypeError: concat() takes 1 positional argument but 2 were given

I read that some pandas version (1.5) allowed to have 2 arguments, but not pandas 2.2.2:

Could it be a bug?

Hi,

It's the known issue for pandas incompatibility. We've fixed it. The fix will be available in the next patch release.
