My data look like:

eval1.head()
0   112
1   98
2   69
3   82
4   91

I wanna create 1D array from that. I've tried:

y_test = eval1.reset_index(drop=True, inplace=True).values
y_test.shape

which raises:

AttributeError: 'NoneType' object has no attribute 'values'

y_test = eval1.values

returns shape

(100, 1)

Since you're setting `inplace=True`, the operation is performed *in-place*, and hence it returns `None` – yatu Aug 25 '20 at 11:05
A dataframe is 2d, a Series or column of a frame is 1d. – hpaulj Aug 25 '20 at 11:37
