python 3.x - ImportError: cannot import name 'joblib' from 'sklearn.externals'

Question

I am trying to load my saved model from s3 using joblib

import pandas as pd 
import numpy as np
import json
import subprocess
import sqlalchemy
from sklearn.externals import joblib

ENV = 'dev'
model_d2v = load_d2v('model_d2v_version_002', ENV)

def load_d2v(fname, env):
    model_name = fname
    if env == 'dev':
        try: 
            model=joblib.load(model_name)
        except:
            s3_base_path='s3://sd-flikku/datalake/doc2vec_model'
            path = s3_base_path+'/'+model_name
            command = "aws s3 cp {} {}".format(path,model_name).split()
            print('loading...'+model_name)
            subprocess.call(command)
            model=joblib.load(model_name)
    else:
        s3_base_path='s3://sd-flikku/datalake/doc2vec_model'
        path = s3_base_path+'/'+model_name
        command = "aws s3 cp {} {}".format(path,model_name).split()
        print('loading...'+model_name)
        subprocess.call(command)
        model=joblib.load(model_name)
    return model

But i was facing this error:

    from sklearn.externals import joblib
ImportError: cannot import name 'joblib' from 'sklearn.externals' (C:UserspraneAppDataLocalProgramsPythonPython37libsite-packagessklearnexternals\__init__.py)

Then i tried installing joblib directly by doing

import joblib

but it gave me this error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 8, in load_d2v_from_s3

  File "/usr/lib64/python3.7/pickle.py", line 1426, in find_class
    __import__(module, level=0)
ModuleNotFoundError: No module named 'sklearn.externals.joblib'

Can you tell me how to solve this? Thanks in advance

Answer 1

You can directly use

import joblib

instead of

from sklearn.externals import joblib.

I tried this out and it worked well for me
