how to check which version of nltk, scikit learn installed?
PythonLinuxShellScikit LearnNltkPython Problem Overview
In shell script I am checking whether this packages are installed or not, if not installed then install it. So withing shell script:
import nltk
echo nltk.__version__
but it stops shell script at import
line
in linux terminal tried to see in this manner:
which nltk
which gives nothing thought it is installed.
Is there any other way to verify this package installation in shell script, if not installed, also install it.
Python Solutions
Solution 1 - Python
import nltk
is Python syntax, and as such won't work in a shell script.
To test the version of nltk
and scikit_learn
, you can write a Python script and run it. Such a script may look like
import nltk
import sklearn
print('The nltk version is {}.'.format(nltk.__version__))
print('The scikit-learn version is {}.'.format(sklearn.__version__))
# The nltk version is 3.0.0.
# The scikit-learn version is 0.15.2.
Note that not all Python packages are guaranteed to have a __version__
attribute, so for some others it may fail, but for nltk and scikit-learn at least it will work.
Solution 2 - Python
Try this:
$ python -c "import nltk; print nltk.__version__"
Solution 3 - Python
In Windows® systems you can simply try
pip3 list | findstr scikit
scikit-learn 0.22.1
If you are on Anaconda try
conda list scikit
scikit-learn 0.22.1 py37h6288b17_0
And this can be used to find out the version of any package you have installed. For example
pip3 list | findstr numpy
numpy 1.17.4
numpydoc 0.9.2
Or if you want to look for more than one package at a time
pip3 list | findstr "scikit numpy"
numpy 1.17.4
numpydoc 0.9.2
scikit-learn 0.22.1
Note the quote characters are required when searching for more than one word.
Take care.
Solution 4 - Python
For checking the version of scikit-learn in shell script, if you have pip installed, you can try this command
pip freeze | grep scikit-learn
scikit-learn==0.17.1
Hope it helps!
Solution 5 - Python
You can find NLTK version simply by doing:
In [1]: import nltk
In [2]: nltk.__version__
Out[2]: '3.2.5'
And similarly for scikit-learn,
In [3]: import sklearn
In [4]: sklearn.__version__
Out[4]: '0.19.0'
I'm using python3 here.
Solution 6 - Python
I needed to do the exact same thing and I found the fastest of the solutions proposed yet. Important: I have Anaconda installed.
In Terminal, type:
python3
Then:
import nltk
And:
nltk.__version__
OUTPUT I am seeing:
'3.5'
Solution 7 - Python
you may check from a python notebook cell as follows
!pip install --upgrade nltk # needed if nltk is not already installed
import nltk
print('The nltk version is {}.'.format(nltk.__version__))
print('The nltk version is '+ str(nltk.__version__))
and
#!pip install --upgrade sklearn # needed if sklearn is not already installed
import sklearn
print('The scikit-learn version is {}.'.format(sklearn.__version__))
print('The scikit-learn version is '+ str(nltk.__version__))
Solution 8 - Python
In my machine which is ubuntu 14.04 with python 2.7 installed, if I go here,
/usr/local/lib/python2.7/dist-packages/nltk/
there is a file called
VERSION
.
If I do a cat VERSION
it prints 3.1
, which is the NLTK version installed.
Solution 9 - Python
Do not use presort='deprecated'
in the below code and it works.
DecisionTreeClassifier(ccp_alpha=0.0, class_weight=None, criterion='entropy',
max_depth=15, max_features=None, max_leaf_nodes=None,
min_impurity_decrease=0.0, min_impurity_split=None,
min_samples_leaf=25, min_samples_split=25,
min_weight_fraction_leaf=0.0, presort='deprecated',
random_state=None, splitter='best')
Checked with version:
>>> import sklearn
>>> print('The scikit-learn version is {}.'.format(sklearn.__version__))
The scikit-learn version is 0.24.1.
