Overflow encountered when evaluating string

I got this error when I am trying to evaluate an expression f(x1, x2, ...) from a string based on given x1, x2, ...

I = eval(string)

<string>:1: RuntimeWarning: overflow encountered in long_scalars

The string represent a very long expression (~ MBs in txt file) and contains huge numbers (>int32), I am wondering how could I solve this? Is there any way to define the data type for the calculation involved in eval (I am guessing int64 probably work)?

Thanks!

Yes, int64 will work.

Please change your int32 to int64.

The maximum value storable in an int32 is 2**31-1
