Assignments are not working

[Hal_Roberts]

I tried running the ungraded lab and am getting a bunch of errors:
C1_W1_Lab_2_iris_classifier.html:1 Access to fetch at ‘file:///C:/data/iris.csv’ from origin ‘null’ has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, isolated-app, brave, https, chrome-untrusted, data, chrome-extension, chrome.

that said I went through the videos several times and built the first assignment. I double checked all dimensions and am getting this error:

I am also constantly getting this error as well:
Failed to load resource: the server responded with a status of 404 (Not Found)

I’m not sure how I can be getting a 404 error when all the files are there.

little frustration as my code should work, I’m happy to post the line for the dimension if I need to. The fact that the practice lab doesn’t work either is concerning…I don’t have much to go off of

Hello,

I am tagging a mentor of this specialisation @Jamal022
Jamal Can you have look at this post.

From what I know 404 error only comes when the files required for you to do assignment are not there or have been deleted. It can also happen if there is tensorflow version discrepancy as this course requires a particular version of tfjs.

/C:/data/iris.csv:1 Failed to load resource: net::ERR_FAILED

this statement tells your assignment and files which requires the browser to read the codes are not in one folders causing these error in your chrome browser.

Make sure you have followed these instructions.

Hey @Hal_Roberts,

Are you using Brackets editor’s built-in local server ?

[Hal_Roberts]

Yes I am, though I also tried it in vs code and that gave me the same errors. The web server for chrome extension is outdated.

[Hal_Roberts]

I have double and triple checked that all the files are paths are correct.

[Hal_Roberts]

If this isn’t the local server then LMK I don’t see any other options

[Jamal022]

Hey @Hal_Roberts,

@Hal_Roberts

It’s the live preview you are right!
Well double check your path and check the ‘/’ and \

[Hal_Roberts]

Yes I have double checked the paths and am still receiving the 404 error. The paths are correct

I have try to fix this myself by changing the url to my server from /data/iris.csv to http://127.0.0.1:5500/ungraded_labs/data/iris.csv which is full path. Then start my live server on ungraded lab directory with F1 using live server extension on vs code not sure this working with others.
