Pandas Rolling Window : Cannot cast array data from dtype('int64') to dtype('int32') according to the rule 'safe'

Question

Trying to use the following to get the mean of a rolling window over pandas :

df['my_variable'] = df \
        .groupby('another_variable') \
        .rolling(window=window_val, min_periods=1)['my_variable'] \
        .mean() \
        .reset_index(drop=True) \
        .values

this piece of code works perfectly fine on my local system [mac], but when i try to run the same on an armv71 system I constantly run into the following :

Exception Type:  Cannot cast array data from dtype('int64') to dtype('int32') according to the rule 'safe'
Traceback (most recent call last):
  File "Pipeline_Code_3.7.py", line 272, in <module>
    .rolling(window=window_val, min_periods=1)['my_variable'] \

I have tried the following :

1. typecasting to int64 like so

   df['my_variable'] = df \
               .groupby('another_variable') \
               .rolling(window=window_val, min_periods=1)['my_variable'] \
               .mean() \
               .reset_index(drop=True) \
               .values.astype('int64')
   

2. checking if the column has any null values and eliminating them, not sure if this helps but was making sure

I assume this a system specific problem, I am not familiar with armv71 because I have not faced this before.
