Facing import error in python backend #7722

Open TheMightyRaider opened 3 days ago

TheMightyRaider commented 3 days ago

Description I'm trying to serve an embedding model [FastText] in triton-server using python as its backend. The external dependencies are just fasttext module which is inturn dependent on numpy. I have created a custom execution environment as mentioned here.

The problem is that, I'm facing the following error while running the triton server as a docker container,

Triton Information I'm running the triton container on a M2 chip and its image is nvcr.io/nvidia/tritonserver:24.09-pyt-python-py3.

To Reproduce

requirements.txt:

fasttext==0.9.3
numpy==2.1.2
pybind11==2.13.6
setuptools==75.2.0

configpb.txt

name: "fast-text-service"
backend: "python"
max_batch_size: 8 

dynamic_batching { }

input [
    {
        name: "TEXT"
        data_type: TYPE_STRING
        dims: [ 1 ]
    }
]

output [
    {
        name: "Status"
        data_type: TYPE_FP32
        dims: [ 1 ]
    },
    {

    }
]

parameters: {
    key: "EXECUTION_ENV_PATH"
    value: {string_value: "/mnt/data/model_repository/fast-text-service/fasttext-server.tar.gz"}
}

instance_group [
    {
        count: 1
        kind: KIND_CPU
    }
]

Expected behavior The container exits by saying error: creating server: Internal - failed to load all models. Below is a segment of a log generated by the triton container,
