ValueError: Cannot convert non-finite values (NA or inf) to integer

Question

df.dtypes
name         object
rating       object
genre        object
year          int64
released     object
score       float64
votes       float64
director     object
writer       object
star         object
country      object
budget      float64
gross       float64
company      object
runtime     float64
dtype: object

Then when i try to convert using :

df['budget'] = df['budget'].astype("int64")

it says:

ValueError                                Traceback (most recent call last)

Answer 1

Assuming that the budget does not contain infinite values, the problem may be because you have nan values. These values are usually allowed in floats but not in ints.

You can:

1. Drop na values before converting
2. Or, if you still want the na values and have a recent version of pandas, you can convert to an int type that accepts nan values (note the i is capital):

df['budget'] = df['budget'].astype("Int64")
