I entered the following code:
import sklearn
import sklearn as sk
import sklearn.preprocessing as skl
from sklearn.preprocessing import Imputer
from sk.preprocessing import Imputer
from skl import Imputer
The part which reads; from sklearn.preprocessing import Imputer gets executed normally.
However, when I run from sk.preprocessing import Imputer, I get the following error:
from sk.preprocessing import Imputer
Traceback (most recent call last):`
File "<ipython-input-84-fc12144914d1>", line 1, in <module>`
from sk.preprocessing import Imputer`
ModuleNotFoundError: No module named 'sk'`
And from skl import Imputer yields the following:
from skl import Imputer`
Traceback (most recent call last):`
File "<ipython-input-85-1e925587d122>", line 1, in <module>`
from skl import Imputer`
ModuleNotFoundError: No module named 'skl'`
Why am I not able to create a shortcut for the Library?
Because it is wrong to do so. The right way do do it is as you have written already.
from sklearn.preprocessing import Imputer
the __init__.py in the preprocessing directory of sklearn defines the possible imports from that level.
The below is a valid aliasing and i think is what you are looking for.
from sklearn.preprocessing import Imputer as imp

Hello there,
I am new to python and I was trying out a project on jupyter notebook when I encountered an error which I couldn't resolve. I'd really appreciate some help.
This is my code:
import pandas as pd
from sklearn.tree import DesicionTreeClassifier
music_data = pd.read_csv(r'C:\python\python382\music.csv')
X=music_data.drop(columns=['genre'])
y=music_data['genre']
model=DesicionTreeClassifier()
model.fit(X,y)
music_data
And i got the output as :
ImportError Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_2540/2462038274.py in <module>
1 import pandas as pd
----> 2 from sklearn.tree import DesicionTreeClassifier #using desicion tree algo here to make model[we import DesicionTree module from tree module which is imported from sklearn library]
3 music_data = pd.read_csv(r'C:\python\python382\music.csv')

5 ##Cleaning and segregating data
ImportError: cannot import name 'DesicionTreeClassifier' from 'sklearn.tree' (C:\python\python382\lib\site-packages\sklearn\tree\__init__.py)
Thank you.
You have missspelled the fumction name DesicionTreeClassifier is in reality DecisionTreeClassifier
I have installed scikit-learn 0.23.2 via pip3, however, I get this error from my code
Traceback (most recent call last):
File "pca_iris.py", line 12, in <module>
X = StandardScaler().fit_transform(X)
NameError: name 'StandardScaler' is not defined
I searched the web and saw similar topics, however the version is correct and I don't know what to do further. The line import sklearn is in the top of the script.
Any thought?
StandardScaler is a method under sklearn.preprocessing. You need to import the StandardScaler like this:
from sklearn.preprocessing import StandardScaler
X = StandardScaler().fit_transform(X)
Or
import sklearn
X = sklearn.preprocessing.StandardScaler().fit_transform(X)
I was trying to draw a linear decision function which separates the two regions of data points in 2d input space using plot_2d_seperator function from figures module, even though figures and other modules have been installed in my device. But it is showing an error attached below.
from sklearn.datasets import make_blobs
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LogisticRegression
from figures import plot_2d_separator
It throws the following error:
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-69-4a72dfe173de> in <module>
2 from sklearn.model_selection import train_test_split

ImportError: cannot import name 'plot_2d_separator' from 'figures' (C:\ProgramData\Anaconda3\lib\site-packages\figures\__init__.py)
I am getting below error when running the code :-
from sklearn.preprocessing import LabelEncorder
LabelEncoder_X = LabelEncorder()
mod_set[:,0] = labelencorder_X.fit_transform(mod_set[:,0])
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

----> 1 from sklearn.preprocessing import LabelEncorder

ImportError: cannot import name 'LabelEncorder' from 'sklearn.preprocessing' (/Users/kenilpatel/opt/anaconda3/lib/python3.7/site-packages/sklearn/preprocessing/__init__.py)
I tried reinstalling scikit as well as updating conda , but nothing seems to work.The problem is with Encorder only , Imputer and other things work fine .
You got a spelling mistake in your module import: LabelEncorder => LabelEncoder
# from sklearn.preprocessing import LabelEncorder
from sklearn.preprocessing import LabelEncoder
scikit-learn seems to work, but when I did:
from sklearn.feature_selection import VarianceThreshold
I got the following error:
ImportError: cannot import name VarianceThreshold
How to bypass this? I am a newbie in Python, so I have no idea what to do.
I played with the order of my imports, as suggested here: ImportError: Cannot import name X, but no luck.
import sys
import pandas as pd
import numpy as np
import operator
from sklearn.feature_selection import VarianceThreshold
from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.feature_extraction.text import HashingVectorizer
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.preprocessing import normalize
from sklearn import decomposition
I am also getting this:
code/python/k_means/serial_version$ python -c 'import sklearn; print(sklearn.VarianceThreshold)'
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'VarianceThreshold'
Version:
>>> import sklearn
>>> sklearn.__version__
'0.14.1'
You can bypass by catching the exception
try:
from sklearn.feature_selection import VarianceThreshold
except:
pass # it will catch any exception here
If you want to catch only Attribue Error Exception then use below
try:
from sklearn.feature_selection import VarianceThreshold
except AttributeError:
pass # catches only Attribute Exception
