Keep getting zero for week 4 Assignment Neural and binary

Hi

I keep getting the following error message and it looks more as if it has to do with the non editable code than my code.

Cell #UNQ_C1. Can’t compile the student’s code. Error: IndexError(‘list index out of range’)
Traceback (most recent call last):

The “non-editable” code implements some tests for your code. If the grader throws an error, it means there is a defect in your code.

In this case, the error is that you have a list index that is out of range.

[TMosh]

The error appears to be in your code for #UNC_C1.

That’s your code for the Sequential model.

Hi

I solved that assignment. I am battling with Module 2, week 4 programming assignment. This is the error message I get.

Cell #13. Can’t compile the student’s code. Error: TypeError(‘only integer scalar arrays can be converted to a scalar index’) Traceback (most recent call last): File “/home/www/app/grading/exceptions.py”, line 112, in handle_solution_errors yield {} File “/home/www/app/grading/abstract.py”, line 393, in _grade context = compiled_code.run(cell_index=cell.index) File “/home/www/app/grading/submission/compiled_code.py”, line 195, in run return list(self._code_items.values())[cell_num - 1].run() File “/home/www/app/grading/submission/compiled_code.py”, line 54, in run return import_module(self.import_statement, items) File “/usr/local/lib/python3.7/importlib/init.py”, line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File “”, line 1006, in _gcd_import File “”, line 983, in _find_and_load File “”, line 967, in _find_and_load_unlocked File “”, line 677, in _load_unlocked File “”, line 728, in exec_module File “”, line 219, in _call_with_frames_removed File “/tmp/student_solution_cells/cell_13.py”, line 15, in best_feature = get_best_split(X_train, y_train, root_indices) File “/tmp/student_solution_cells/cell_12.py”, line 77, in get_best_split information_gain = compute_information_gain(X, y, node_indices, feature) File “/tmp/student_solution_cells/cell_12.py”, line 67, in compute_information_gain subset_indices = node_indices[X[node_indices, feature] == value] TypeError: only integer scalar arrays can be converted to a scalar index

Please post a screen capture image. I cannot read that pile of text and get the lines separated correctly.

[Gideon_Jesse_Slabber]

Here you go, thank you very much!

[TMosh]

There is a problem in this line of code in your compute_information_gain() function:

I believe the issue is that X only has one index, but you’re providing two. And maybe also there is a problem with the “value” variable.

[Gideon_Jesse_Slabber]

Thank you I will give it a try and let you know how it goes.
