Adding Decision Forests Op

[mmiller8878]

I just came across this issue - @grantstephens I'm not sure if you ever got this working but Tensorflow serving, as of version 2.11.0, natively supports Tensorflow Decision Forests.

@emacski Any chance you fancy making some new Docker images based upon Tensorflow serving 2.11.0 so we can get Decision Forests on M1? :) I am not yet on M1 but have colleagues who need this!

[emacski]

Thanks for the note of appreciation!

Additional tensorflow ops for tensorflow-serving-arm is something I have not yet considered, so it's very possible it's just not supported in this project yet. I'll have a look over those instructions and with a little luck hopefully it will be straight forward to implement support here.

As for the images, if I am building all arches (which I don't do too often), I tend to just run something like:

bazel run //tensorflow_model_server:project_image --config=release --config=linux_amd64_avx_sse4.2 && \
bazel run //tensorflow_model_server:project_image_debug --config=release --config=linux_amd64_avx_sse4.2 && \
bazel run //tensorflow_model_server:project_image --config=release --config=linux_arm64_armv8-a && \
bazel run //tensorflow_model_server:project_image_debug --config=release --config=linux_arm64_armv8-a && \
bazel run //tensorflow_model_server:project_image --config=release --config=linux_arm64_armv8.2-a && \
bazel run //tensorflow_model_server:project_image_debug --config=release --config=linux_arm64_armv8.2-a && \
bazel run //tensorflow_model_server:project_image --config=release --config=linux_arm_armv7-a_neon_vfpv4 && \
bazel run //tensorflow_model_server:project_image_debug --config=release --config=linux_arm_armv7-a_neon_vfpv4 && \
bazel run //tensorflow_model_server:project_image --config=release --config=linux_arm_armv7-a_neon_vfpv3 && \
bazel run //tensorflow_model_server:project_image_debug --config=release --config=linux_arm_armv7-a_neon_vfpv3

publishing (multi-arch manifest creation) is scripted in:
tensorflow_model_server/tools/ci/publish.sh

[emacski]

ok, one thing to try before digging deeper:

follow all proposed instructions except for this modification:

instead of changing tensorflow_model_server/BUILD as the instructions suggest, can you try incorporating the target label into deps for the main_lib target?

tensorflow_model_server/BUILD

...
cc_library(
    name = "main_lib",
    srcs = [
        "main.cc",
    ],
    linkstamp = "stamp.cc",
    deps = [
        "@org_tensorflow//tensorflow/c:c_api",
        "@org_tensorflow//tensorflow/compiler/jit:xla_cpu_jit",
        "@org_tensorflow//tensorflow/core:lib",
        "@org_tensorflow//tensorflow/core/platform/cloud:gcs_file_system",
        "@org_tensorflow//tensorflow/core/platform/hadoop:hadoop_file_system",
        "@org_tensorflow//tensorflow/core/platform/s3:s3_file_system",
        "@tf_serving//tensorflow_serving/model_servers:server_lib",
        "@org_tensorflow_decision_forests//tensorflow_decision_forests/tensorflow/ops/inference:kernel_and_op",
    ],
)
...

Thank you for the reply
So far I've been trying to do it with a couple of patches which doesn't seem to be working.
I'll give your method a go next- I just don't know where to add the SUPPORTED_TENSORFLOW_OPS part and how to add the extra compile args (use_tensorflow_io for example).

[grantstephens]

Ok, you were spot on- adding that into that build file cause the df stuff to be build, but it seems to error:

In file included from external/ydf/yggdrasil_decision_forests/dataset/data_spec.h:35:
external/ydf/yggdrasil_decision_forests/utils/compatibility.h:120:18: error: no matching constructor for initialization of 'std::__1::vector<yggdrasil_decision_forests::model::proto::VariableImportance, std::__1::allocator<yggdrasil_decision_forests::model::proto::VariableImportance>>'
    new (&data_) T(std::move(data));
                 ^ ~~~~~~~~~~~~~~~

This is what I have so far. I am then trying to compile it with:

bazel run //tensorflow_model_server:project_image --define use_tensorflow_io=1 --define no_absl_statusor=1 --config=linux_amd64_avx_sse4.2

My suspicion is that the use_tensorflow_io and no_absl_statusor from here aren't being passed through.

Appologies for documenting this here and I don't expect this repo to support this in the end, but more than willing to add any findings to a readme in the end.

[emacski]

can you post the compile command that generates the above error?

[grantstephens]

This one?
