Error in sampling the data

[parvaneh-soleimany]

Hey. I am facing error on sampling data.
I get error: "Breaking the generation loop!"
and when I checked the code I understood in the next line, df_gen gets empty and it is obviously because the model just generated placeholder, and not the desired data.
df_gen = df_gen[~(df_gen == "placeholder").any(axis=1)]

I am working on it for more than one week but I couldn't handle it.
Can you please help me? I am really in need of this code to works.
My data is a tabular text data, each column consisting number or piece of text (sometimes long texts).

Thank you in advance.
