ImportError: cannot import name cross_validation
(4 answers)
Closed 4 years ago.
Here is my code Please Help. I'm a beginner.
import pandas as pd
import sklearn
from sklearn.feature_selection import SelectFromModel
from sklearn.ensemble import ExtraTreesClassifier
from sklearn.metrics import confusion_matrix
from sklearn.model_selection import train_test_split
from sklearn import cross_validation
I'm using the latest version of Sklearn but I'm getting this error
On Windows:
Traceback (most recent call last): File "MalwareDetector.py", line
8, in
from sklearn import cross_val_score ImportError: cannot import name 'cross_val_score' from 'sklearn'
(C:\Users\richa\AppData\Local\Programs\Python\Python37-32\lib\site-packages\sklearn__init__.py)
On Ubuntu:
Traceback (most recent call last): File "MalwareDetector.py", line 8,
in from sklearn import cross_validation ImportError: cannot
import name cross_validation
cross_validation is deprecated since version 0.18. This module will be removed in 0.20.
Use sklearn.model_selection.train_test_split instead.
from sklearn.model_selection import train_test_split

Trying to run some machine learning examples so am importing some packages
sklearn version 0.22.1
tensorflow version 2.3.0
keras version 2.3.0
in the following way:
import os
import sys
import math
import numpy as np
import pandas as pd
from sklearn.preprocessing import MinMaxScaler
from keras.models import Sequential
from keras.layers import Dense, LSTM
import matplotlip.pyplot as plt
I am getting the import error:
ImportError: cannot import name 'Sequence'

I have looked on line for help trying a few different tensorflow and keras versions. I have also tried:
import tensorflow.keras as keras
and import tensorflow.keras.utils import Sequence
without success
I am trying to run ID Card Segmentation (MIDV-500) on my Ubuntu machine.
I need to run some files, and one of them is "train.py".
when i run "train.py" i get an error message on the Import section.
(the full repository - https://github.com/AdivarekarBhumit/ID-Card-Segmentation)
i try to import:
import cv2
import numpy as np
from sklearn.model_selection import train_test_split
from keras.callbacks import TensorBoard, ModelCheckpoint
from .unet_model import get_model
the error on the Terminal:
/Downloads/ID-Card-Segmentation/model$ python train.py
Using TensorFlow backend.
Traceback (most recent call last):
File "train.py", line 5, in <module>
from .unet_model import get_model
ModuleNotFoundError: No module named '__main__.unet_model'; '__main__' is not a package
how to fix that?
I've seen so many questions about this error online, but even after reading through all of them, I have no idea why I am still getting this error. I have spicy installed, and I am completely lost as to what to do. All I'm trying to do is get an example working that I found online, but this ModuleError keeps appearing.
Here are the imports below:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.colors import Normalize
from sklearn.svm import SVC
from sklearn.preprocessing import StandardScaler
from sklearn.datasets import load_iris
from sklearn.model_selection import StratifiedShuffleSplit

Any suggestions would be appreciated so much!! I am using Mac OS, and I have 3.7 python installed through Anaconda.
Try creating a fresh environment and install your packages with conda.
conda create -n testenv python=3.7 matplotlib numpy scikit-learn scipy
Then run your code within this environment.

Kindly provide me the solution.I am using Python 3.8.2 and IDLE 3.8.32
Seems it is an issue with the latest version of pandas.
Try installing an older version:
pip uninstall pandas
pip install pandas==1.0.1

When you try to ask something on StackOverflow, you should provide your relevant code, not the error message only. It would help people reproduce your problem.
About your problem, it seems that you've written this
from model_selection import train_test_split
model_selection is a sub-module of sklearn. So you have to call it via sklearn like this:
from sklearn.model_selection import train_test_split
