I think you are trying to convert your dataset into an integer. But before trying to convert a suspicious variable to an integer, first, check the type of variable.
For example you can see the below code.
>>> text = '101.10'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '101.10'
>>> f = float(text)
