[samthakur587]

fixed the test case failing at paddle backend in ivy.equal

tested in local all tests are passing except paddle but paddle it self have this bug ivy don't have any problem. i have raised a bug on paddle you can see here. here

here the test result .

# TODO enable
        # if ivy.is_ivy_container(ret_np) and ivy.is_ivy_container(ret_from_gt_np):

        # else:
        if ret_np.dtype == "bfloat16" or ret_from_gt_np.dtype == "bfloat16":
            ret_np = ret_np.astype("float64")
            ret_from_gt_np = ret_from_gt_np.astype("float64")
