Load model pre-trained with joblib

Deployment

I’m trying to load a neural network model in my streamlit app, but it appears the error:

Traceback (most recent call last):
  File "/home/appuser/venv/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 565, in _run_script

    exec(code, module.__dict__)

  File "/app/dry_forest_fire/interface.py", line 20, in <module>
    rede_neural = joblib.load('Models/rede_neural')

    obj = _unpickle(fobj, filename, mmap_mode)

  File "/usr/local/lib/python3.9/tarfile.py", line 1625, in open
    raise ReadError("file could not be opened successfully")
tarfile.ReadError: file could not be opened successfully

The other model which I just used random forest loads ok (I also verified the path). I’m trying to load the neural network like this:

import base64
import streamlit as st
import plotly.express as px
import pandas as pd
import numpy as np
import joblib
from sklearn.preprocessing import StandardScaler

neural_network= joblib.load('Models/rede_neural') #Not ok
floresta_aleatoria = joblib.load('Models/floresta_aleatoria') #Load ok


------- Requirements.txt -------
joblib==1.1.1
numpy==1.19.4
pandas==1.4.4
plotly==5.13.1
scikit_learn==1.2.1
streamlit==1.19.0
typing-extensions==3.10.0.0
tensorflow>=2.6.3
tensorflow-cpu>=2.6.3

Can anyone help me about this? Ps.: the local script is running normal

Hi @victoresende19! :wave:

Good to see you back on our forums! :blush:

While this is difficult to diagnose as I haven’t got the full code, here are a few things you may want to double-check:

  1. Verify the file path: Double-check that the path Models/rede_neural is correct and that the file exists in the specified location.

  2. Check file permissions: Ensure that the file has appropriate read permissions for the user running the Streamlit app. You can check and adjust the permissions using the ‘ls -l’ command in a terminal.

  3. Confirm that the version of Keras used to save the model is compatible with the version installed in your environment.

Let us know how it goes.

Best wishes,
Charly
