I have this code:
df = pd.read_csv("Fatalities.csv")
training_data, testing_data = train_test_split(df, test_size=0.75, random_state=20)
df["fatal"] = pd.to_numeric(df["fatal"], downcast="float")
Y = training_data["fatal"]
X = training_data.drop(columns=["fatal"])
reg = linear_model.LinearRegression().fit(X,Y)
I keep getting could not convert string to float. But if I run only the 3rd line and print(df.dtrypes) it shows my "fatal" variable as float.
