How do i resolve

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]

error in line 45

how to resolve it

[Walter Roberson]

@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.

[Mohammed Lafoui]

I cannot submit all my exercices, error of path in windows!!!? how to repair this? please

Answer 1

[Abhishek Malik]

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!

[Tom Mosher]

I recommend you not change the script files.

Instead, download the correct set from the course resources.

There are different sets for MATlAB and Octave users.

[Ramon Andino]

When I click on the zip file , there is only one zip set. Not multiple.

[Si Tong Ngo]

same, is there a way to get the set for matlab?

[lavanya s]

i changed it according to the following changes but it did not work for me

[Harshad Koshti]

it's not working..

[Ivan Belikov]

Also you have to change:

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

Line 37: showFeedback(parts_1, response);

[Satishkumar Bansode]

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

  addpath('./lib/jsonlab');

[KAOUTAR MOUHCINE]

thank you so much ... it works

[TIANXIN LI]

It works to me. Thank you!

[José Díaz]

It didn't work for me

[Mike Ak]

I did change all above but still get below error

>> submitWithConfiguration

Not enough input arguments.

Error in submitWithConfiguration (line 4)

parts_1 = parts(conf);

[Mike Ak]

I get the same error too even i did follow all above gudlines

>> submitWithConfiguration

Not enough input arguments.

Error in submitWithConfiguration (line 191)

parts_1 = parts(conf);

[urvi vasisht]

error in line 94 is coming pls tell

[Walter Roberson]

You need to name a struct when you call submitWithConfiguration -- the "configuration" that you are submitting with! You cannot just call submitWithConfiguration by itself. The submit() function builds the configuration for you

[Ajay Kumar]

can u send the code

[Ajay Kumar]

getting this error can anyone resolve it

[Amitabh Kant]

Also you have to change:

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

Line 37: showFeedback(parts_1, response

[Nick Tsui]

Thanks!

Answer 2

[Peter Radi]

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

Answer 3

[Nathan Abraham]

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

[Tom Mosher]

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.

[Ramon Andino]

I am using zip download from week2

[Walter Roberson]

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

Try giving the command

I'm having the same issue, attempted this without success. Has anyone solved this?

Thanks

Dan Cav:

Could you confirm that you are using a submitWithConfiguration.m that defines function parts() around line 93 or so, and yet submitWithConfiguration is not able to find parts ?

What shows up for

which -all submitWithConfiguration

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]

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
