I am reading in a CSV file as a DataFrame while defining each column's data type. This code gives an error if the CSV file has a blank row in it. How do I read the CSV without blank rows?

dtype = {'material_id': object, 'location_id' : object, 'time_period_id' : int, 'demand' : int, 'sales_branch' : object, 'demand_type' : object }

df = pd.read_csv('./demand.csv', dtype = dtype)

I thought of one workaround of doing something like this but not sure if this is the efficient way:

df=pd.read_csv('demand.csv')
df=df.dropna()

and then redefining the column data types in the df.

Edit : Code -

import pandas as pd
dtype1 = {'material_id': object, 'location_id' : object, 'time_period_id' : int, 'demand' : int, 'sales_branch' : object, 'demand_type' : object }
df = pd.read_csv('./demand.csv', dtype = dtype1)
df

Error - ValueError: Integer column has NA values in column 2
