submit

'parts' requires one of the following:

Navigation Toolbox

Robotics System Toolbox

Sensor Fusion and Tracking Toolbox

Error in submitWithConfiguration (line 4)

parts = parts(conf);

Error in submit (line 30)

submitWithConfiguration(conf);

@Kasula varshini

Install one of: Navigation Toolbox, Robotics System Toolbox, or Sensor Fusion and Tracking Toolbox. That will resolve the error. (You would then get a different error.)

The permanent solution is as others have describe:

download repaired files from your course software; or
edit the code so that it does not use parts as both a variable and the name of a function.

This is happening because variable parts has the same name as of parts(conf) function in file ex1/lib/submitWithConfiguration.m

Make the following changes to resolve this :

Line 4 - parts_1 = parts(conf);

Line 92 - function [parts_1] = parts(conf)

Line 93 - parts_1 = {};

Line 98 - parts_1{end + 1} = part;

Basically, I've just renamed the variables.

Same thing is happening with one more variable, so make the following changes :

Line 66 - submissionUrl_1 = submissionUrl();

Line 68 - responseBody = getResponse(submissionUrl_1, body);

This should work!

please replace the following code for ex1/lib/submitWithConfiguration.m. this will work 100%

Also you have to change:

Line 22: response = submitParts(conf, email, token, parts_1);

Line 37: showFeedback(parts_1, response

Just replace submitWithConfiguration.m's content with a previous version of it (like from ex4).

I changed the name of the function parts() to parts_1(). Try doing the same for the definition and the call for the function.

It seems that the name of the function parts in MATLAB is dedicated name to some other toolbox.

It worked for me.

Tnx

Better to download the correct set of programming exercise script files.

There are two sets available. MATLAB users should get the ones from the setup instructions for MATLAB Online in Week 2.

parts is a function defined inside submitWithConfiguration

See for example line 93 at https://github.com/tuanavu/coursera-stanford/blob/master/machine_learning/exercises/matlab/submitWithConfiguration.m

I know, even I have the same file in the same path. But want to know why it is executing normally. As I have just downloaded and uploaded the zip file on matlab online and after unzipping I am trying to submit the code.

function submitWithConfiguration(conf)
% Note: has the "certificate" patch from Liran for Windows-like systems
  addpath('./lib/jsonlab');

  fprintf('== Submitting solutions | %s...\n', conf.itemName);

Could you confirm that you are using a submitWithConfiguration.m that defines function parts() around line 93 or so ?

Mansi Patel 2019-10-13

编辑：Mansi Patel 2019-10-13

yes

in line 93 : parts = {};

Hi,

I followed the directions where I changed parts to parts_1, but when I submitted I get the following error.

Function: parts

FileName: /MATLAB Drive/machine-learning-ex3/ex3/lib/submitWithConfiguration.m

LineNumber: 94

Please correct your code and resubmit.

fline num 94 is :

for partArray = conf.partArrays

vishnu vardhan sreerlavancha 2021-6-20

Hi Nimisha,

Please check all the references of 'parts' variable and replace in all places.

And also check 'submissionUrl = submissionUrl()'

replace 'submissionUrl_1 = submissionUrl()'

Check all the refences where we are calling submissionUrl and replace with submissionUrl_1

Hope this is helpful.

Thank you
