My OS is Ubuntu, and I've followed the official installation guide to install lightgbm. However, when I import it, this error is raised:
ImportError: No module named lightgbm
How can I solve this?
Do I also need to go to /python-package folder to run setup.py after running those linux commandlines?
I had the same problem, and solved running the installation directly on the notebook
!pip install lightgbm
Besides running those linux command lines. I also need to go to /python-package then run 'python setup.py install'.
conda install -c conda-forge lightgbm solved the problem for me
you need just run in a notebook cell before importing
For Windows users, VC runtime <https://go.microsoft.com/fwlink/?LinkId=746572> is needed if Visual Studio (2015 or 2017) is not installed.
Install wheel <http://pythonwheels.com> via pip install wheel first. After that download the wheel file and install from it:
pip install lightgbm
The following should do the trick:
export PATH=/usr/local/bin/anaconda3/bin${PATH:+:${PATH}}
PYTHONPATH=$PYTHONPATH:/usr/local/bin/anaconda3/lib/python3.6/site-packages
Note that you might need to change the paths if you are using a different Python version.
Thank you for above question and answers, had a similar issue.
Problem:
After successfull install of lightgbm, I was getting the error ImportError: No module named 'lightgbm' (in Jupyter Notebook on Google Cloud's Notebook Instance in AI Platform project).
Issue:
Realized that the install of lightgbm was in Python 2.7 even when the notebook was running in Python 3 (path: './.local/lib/python2.7/site-packages').
Solution:
The error was gone after the Jupyter Notebook was set to run on Python 2 instead of Python 3.
within Jupyter Notebook cell is: try running
import sys
!{sys.executable} -m pip install lightgbm
With python try, from pypi.org, this line
pip install lightgbm
or
pip3 install lightgbm
Also, you can try this one if you use anaconda
conda install lightgbm

Did pip install pdfrw, uninstalled and reinstalled, restarted my laptop, but still unable to import the specified package as it returns error: No module named 'pdfrw'.
https://pypi.org/project/pdfrw/#pdfrw-philosophy
Any advice is appreciated.
Update: Tried installing by cmd, I'm using Jupyter Notebook as IDE :)
You have to make sure that the Python that you are using with Jupyter Notebook is the same that the one for which you are installing that package. If you have several Python interpreters installed or if you installed Ananconda to use Jupyter, you have to take care of which pip are you invoking from CMD.
If you are using Jupyter from Ananconda, try to install the package using conda.
conda install pdfrw
Another thing that you can do is open a Command Prompt and type:
where python
you will get the path to the interpreters that you have installed. In my case I get:
>>> C:\Windows\system32>where python
C:\Python39\python.exe
C:\Python38\python.exe
>>> C:\Windows\system32>where pip
C:\Python39\Scripts\pip.exe
C:\Python38\Scripts\pip.exe
Then you can use a concrete interpreter to call pip, in my case I will do:
C:\Python39\python.exe -m pip install pdfrw
After the installation finish, invoke the same interpreter you use to call pip:
C:\Python39\python.exe
Then try to import pdfrw. If you can import it, then the problem is that you are using a different interpreter in Jupyter Notebook.
from libsvm import svmutil
ImportError: No module named libsvm
I have the module libsvm installed. Because when I run pip3 install libsvm, I see this:
Requirement already satisfied: libsvm in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (3.23.0.4)
So what's causing the error?
make sure you are using the same python version, when you install the library and you run it. fyi, pip3 is for python 3.
my suggestion is create new virtual environment and activate then install all library that needed, then run your app from there.
Try the followings, it may solve the problem:
0- Run your code with Python version 3 and above. (python3 yourFile.py in the terminal)
1- pip3 install libsvm
2- pip install -U libsvm-official
Currently I'm trying to install tensorflow with pip, I've used the following command to install it with:
pip3 install --user --upgrade tensorflow which after installing returns Successfully installed tensorflow-2.5.0. But when I install I get a lot of notices "Requirement already satisfied" but I'm unsure if this is normal or not.
I have a following local python file on my Windows 10 computer called test.py and inside is a simple import
test.py
import tensorflow as tf
When I run python I get the following error:
import tensorflow as tf
ModuleNotFoundError: No module named 'tensorflow'
When I run pip3 list I can see that the module tensorflow is there, but importing it does give the error. It seems to happen with other modules too, as I've tried installing pymongo and it gave me the same error.
What I've tried
Uninstalling, re-installing python
Uninstalling and re-installing tensorflow
Python3 version: 3.9.5
Pip3 version: 21.1.1
I would try python3 -m pip install tensorflow. Running pip as a module ensures the versions are the same and can help with compatibility.
Most probably you have installed tensorflow on python3(guessing after seeing pip3 command) but you are running script on python2 (guessing after seeing "When I run python").
Assuming you aren't using virtualenv
Try running
python3 test.py
If this didnt help then try below command.
python3.x test.py # where x could be your minor version Ex: python3.6/python3.7
I have recently installed Anaconda with Python 3.5 and all the rest. I come from R where I am used to install packages dynamically. I am trying to install a module called scitools through jupyter notebook. I would like to recreate this in jupyter. However, I don't know how to dynamically install packages (if it's possible). I would greatly appreciate your help. Thank you!
EDIT: I am trying to use conda as recommended by the community, but it's not working. I am using mac OSX
Check Jake Vander Plus Blog here to learn how to install a package with pip from Jupyter Notebook.
# Install a pip package in the current Jupyter kernel
import sys
!{sys.executable} -m pip install numpy
So if you have already done the install with anaconda, you may already have the module installed. In that case in your jupyter notebook after you have activated your kernel, you just need to make sure you execute the import statement.
import scitools
If you haven't installed that module yet, you can install it one of two ways. Both work from your command line or terminal.
pip install scitools
or since you have Anaconda
conda install scitools
and that should do it. Your import statement in your notebook when executed should correctly locate and enable the use of that module.
I had the same issue. It turns out if you open an anaconda window, which in Windows is accessible under the Anaconda drop down, it points to the correct location to install (or update) using pip.
Not able to install gensim on windows.Please help me I need to gensim Immediately and tell me installation steps with More details and other software that needs to be installed before it. thanks
First you need to install NumPy then SciPy and then Gensim (assuming you already have Python installed). I used Python 3.4 as I find it easier to install SciPy using version 3.4.
Step 1) Install Numpy:
Download numpy‑1.13.1+mkl‑cp34‑cp34m‑win32.whl from here
note that in cp34-cp34m 34 is version of Python you are using. So download appropriate file
Open command prompt and go the folder in which you just downloaded the file and install Numpy using following command:
pip install numpy‑1.13.1+mkl‑cp34‑cp34m‑win32.whl
You should get successfully installed numpy message
Step 2) Install SciPy:
Follow the same link as above and download the scipy‑0.19.1‑cp34‑cp34m‑win32.whl file.
Install it using the same instructions than in Step 1 but with this file name. The command is the following:
pip install scipy‑0.19.1‑cp34‑cp34m‑win32.whl
You should get this message successfully installed scipy
Step 3) Install gensim:
Follow the link in step 1 and download gensim‑2.3.0‑cp34‑cp34m‑win32.whl (the appropriate version for your system)
Install it using the instructions in Step 1 (with this file name) with following command:
pip install gensim‑2.3.0‑cp34‑cp34m‑win32.whl
You should get this message successfully installed gensim
Now in a Python shell try:
import gensim
It should be successfully imported
NOTES:
Make sure pip is in your environment variables (add C:\python34\scripts to your environment variable).
Make sure to download all the packages according to the Python version you are using.
gensim depends on scipy and numpy.You must have them installed prior to installing gensim. Simple way to install gensim in windows is, open cmd and type
pip install -U gensim
Or download gensim for windows from
https://pypi.python.org/pypi/gensim
then run
python setup.py test
python setup.py install
I struggled with this a bit today trying to figure out if I needed a python 2.7 environment or if I could use my 3.5. I ended up doing this from an Anaconda 3.5 install:
conda install -c anaconda gensim=0.12.4
After a few hours of trying various things, suddenly it all worked on 3.5. My error was that it kept failing to install Scipy. I tried starting over with the conda install and just worked.
See: https://anaconda.org/anaconda/gensim
I strongly suggest using anaconda where the installation of all the packages is very easy.
The command for installing genism and all of its necessary packages on windows using anaconda python 3.7 is below.
conda install -c anaconda gensim
I followed the instruction on https://radimrehurek.com/gensim/install.html which then successfully installed the fast version of Gensim (3.8.0) on Windows:
conda install -c conda-forge gensim
PS:
The following did NOT install the fast version on Windows:
conda install gensim
After attempting some of the above ideas, there was still a "hiccup" with gensim but the error was something else related to punkt. The following (where the interest is the second line)...
import nltk
nltk.download('punkt')
import numpy
import scipy
import gensim
...did the trick. I used conda and not pip but do not believe that mattered.
