[11happy]

Overview:

• This PR implements support for numpy.bincount operation

Testing:

• Ensured all tests are passing & other functionalities remain unaffected.

CC:

• @rkazants

Here there are two things I am not sure about :

• sparse arguement I did not find its documentation on the official numpy docs
  

• Here while getting the max_element using reduce_max op I have set the reduction_axes=[0] assuimg 1D input tensor as mentioned in numpy docs

Thank you

Hii :)
could you please help me how to resolve this issue, thank you

FAILED keras/src/ops/numpy_test.py::NumpyDtypeTest::test_bincount_uint32 - ValueError: unsupported type of `x` to create ov.Output: <class 'NoneType'>

[nikolasavic3]

have you tried testing locally? Does it work for you?
you can do:
pytest keras/src/ops/numpy_test.py::NumpyDtypeTest::test_bincount_int16

yes everytime locally i run this command
pytest -c ./pytest.ini ./keras/src/ops/numpy_test.py
& its passing

I had the same problem.
I wrote this in the terminal and after that tests started failing locally too:
export KERAS_BACKEND=openvino
and this if you don't have a GPU:

export JAX_PLATFORMS=cpu
export XLA_FLAGS=--xla_gpu_cuda_data_dir=""

You can then test like this:
pytest keras/src/ops/numpy_test.py
or this:
pytest keras/src/ops/numpy_test.py::NumpyDtypeTest::test_bincount_int16

if you want to fix a mistake in a file without doing a new commit you can do:

git add keras/src/backend/openvino/numpy.py # after you fix the mistake in the file
git commit --amend --no-edit # you can commit having all changes within the last commit
git push --force-with-lease

thanks for constantly helping me on this PR, I didnt knew about --force-with-lease I will try it next time, I currenlty did rebase while squashing all commits & force pushed it.

Gentle Ping! @fchollet , @rkazants .
I have fixed the merge conflicts & openvino CI issues.
Thank you

[rkazants]

please revert these changes

[11happy]

Earlier the openvino CI was failing because of this as in the implementation of expand_dims if input is not an instance of openvinokerastensor it was going in else statement causing a false assert.

[rkazants]

Here you should only remove lines corresponding to bincount tests.
Now you are adding for average for some reason

[11happy]

sorry, while resolving the merge conflict I took a merge with the master branch and it was an incoming change so I did kept a combination of both current and incoming, I will remove it.
Thank you
