Text artifact not found

[zfallahnejad]

I want to add a text artifact to my service. I successfully packaged the file and created the bundle. When I try to serve the bundle, I get an error message saying that the file is not found! This problem only happened with text artifacts, as my sklearn model worked properly. Do you know what the problem is? The version of bentoml I'm using is 0.13.1.

bentoml_packer.py:

import os
import joblib
from ml_server import MLServices

def load_model(model_path):
    return joblib.load(model_path)

sa_model = load_model('./artifacts/sentiment_analysis_model/model.joblib')

services = MLServices()
services.pack("sentiment_analysis_model", sa_model)
services.pack("forbidden_data", './artifacts/forbidden_data/word_list.txt')
services.pack("singular_data", './artifacts/singular_data/exception_words_list.txt')

saved_path = services.save(
    version='1.0.0',
)

ml_server.py:

...
@artifacts([SklearnModelArtifact('sentiment_analysis_model'),
            TextFileArtifact('forbidden_data', file_extension=".txt", encoding="utf-8"),
            TextFileArtifact('singular_data', file_extension=".txt", encoding="utf-8")])
class MLServices(BentoService):
...

docker-compose.yml:

version: '3.7'
services:
  bentoml:
    build: /home/aincl/bentoml/repository/MLServices/1.0.0
    ports:
      - "5000:5000"
    deploy:
      mode: global
    restart: on-failure

hello @zfallahnejad

Thank you for raising the question. I am sorry about the late respond

For the text artifact, you will need to send the content of the txt file to pack instead of the file path to the content.

For example:

svc = MyService()

with open('path/to/my/text/file', 'r') as file:
     content = file.read()

svc.pack('my_text_file', content)

Let me know does this help you.
