Hi Vlad,
Further to my previous issue 'synthetic dataset generation by housetype',
this new issue reports a different problem specific to household type 'c0'.
I should have said that in the previous issue I'm generating 10000 rows, and also here.
I wanted to attached the python here but the PyCharm export from a .iypynb file creates a .html file.
Github won't allow .html attachments, so I'll send you the .html file via GU email.
The error occurs after the 100% progress report from
new_data = _syn.generator()Here is the output up to the error
Here is the error report
