ValueError: 'a' must be greater than 0 unless no samples are taken

[QABoahene]

I was trying to use this same concept for my dataset and got the error in the title. Could anybody help? I also checked the shape of the dataframe which was (56, 11).

The error message is below:

---

ValueError Traceback (most recent call last)

----> 2 hps = data.loc[data['polarity'] == 0.3, ['titles']].sample().values
3 for h in hps:
4 print(h[0])
