I have MAC and facing issue in building addons. So, I tested code in colab.

Please let me know what will be my next steps. To do as far as I know will be to add test for the same.

[Squadrick]

@SSaishruthi A few changes. Also, you need to update the following: __init__.py, README.md and create tests.

[SSaishruthi]

Thanks @Squadrick
Will update soon

[SSaishruthi]

@Squadrick
Updated changes. I will work on test cases.

[SSaishruthi]

Added test cases

[Squadrick]

@SSaishruthi You need to add this to run the test cases in graph and eager mode.

[SSaishruthi]

@Squadrick I have added test scripts in PR. Do you mean to add this line?

[Squadrick]

You need to update the following files: __init__.py, BUILD and README.md

[SSaishruthi]

@SSaishruthi I'm gonna trigger the pre-submit tests, you might have to make a few more changes after that.

[Squadrick]

Also, your code fails the sanity check. Use make code-format like mentioned here to format code.

[SSaishruthi]

Hi @Squadrick

Updated code as per the comments.

[Squadrick]

@SSaishruthi Looks good, thanks for the contribution. I'm gonna trigger the tests again.

[Squadrick]

@SSaishruthi Your BUILD file formatting is incorrect, once you fix that the tests should pass.

[SSaishruthi]

@Squadrick
I think I have missed , in BUILD. Updated now. Can you please trigger the test?

[SSaishruthi]

@Squadrick Thanks for the review and helping me through this.
