The TypeError: object of type 'NoneType' has no len()

[geeeekDing]

When I used the hyperas to adjust the paraments of ANN, It returns the" TypeError: object of type 'NoneType' has no len()", I don't know the cause of this problem. The train data and test data can be used in kreas.

......... Hyperas search space:

def get_space(): return { 'Dense': hp.choice('Dense', [40, 80, 150]), 'Dense_1': hp.choice('Dense_1', [40, 80, 150]), 'Dense_2': hp.choice('Dense_2', [40, 80, 150]), 'Dense_3': hp.choice('Dense_3', [40, 80, 150]), 'Dense_4': hp.choice('Dense_4', [40, 80, 150]), 'Dense_5': hp.choice('Dense_5', [40, 80, 150]), 'Dense_6': hp.choice('Dense_6', [40, 80, 150]), 'epochs': hp.choice('epochs', [25, 50, 75, 100]), 'batch_size': hp.choice('batch_size', [100, 300, 500 ,700]), }

Thank you

Hello everyone， when I run a program that can be executed successfully, I found that ：len(determine_indent(data_string))=4, the type of "determine_indent(data_string)" is "str"，and I run my program ,it returns error,and the type of "determine_indent(data_string)" is NoneType

I made a change that I set len(determine_indent(data_string)) =4, because of my the length of the indent of function "data()" is 4, My program is already running, but where is the original question of its

Hi did you solve this error ?
