i am new to python. i am using python 3.7 and installed pandas using pip. when i checked for pandas version i found all the dependencies are not installed . so i read somewhere anaconda installation will install all the dependent packages. so i have installed anaconda still when i search for python version it shows that packages are not installed
Pandas version image
i am using visual studio code for programming python
i want to use pandas with full functionality
can someone help me on this installation
thank you
The process I follow:
Install anaconda from this link https://www.anaconda.com/distribution/
Add the Anaconda program directory to your Path environment variable. See here > https://www.quora.com/How-can-I-add-conda-command-into-the-PATH-environment-variable-so-that-it-recognizes-the-instruction-given-that-the-executable-program-is-already-installed
Sometimes you may also need to add ".....Anaconda3\Library\bin" as well.
Open command prompt and type "conda install pandas", to install pandas.
This has always worked for me.
I want to import numpy and pandas in jupyter but I get the message:
----> 1 import pandas as pd
ModuleNotFoundError: No module named 'pandas'
Now when I open the anaconda prompt and do pip list then I can see the latest version of numpy
Even when I say pip install it says requirement already satisfied.
I know that this relates in some way to the PATH of python.
Honestly as someone from a math background learning how to code I'm really unsure what this means and how I can check and fix whether the Path is correct or not.
Does it just mean where jupyter looks for python.exe? I dont know for sure where to check for this.
where python in the Anaconda Prompt gives me:
C:\Users\MyName\Anaconda3\python.exe
C:\Program Files\Python37\python.exe
When I run this on the jupyter notebook:
from jupyter_core.paths import jupyter_data_dir
print(jupyter_data_dir())
I get:
C:\Users\NyName\AppData\Roaming\jupyter
Is this the source of the problem?
The problem is that your Jupyter kernel is using a different Python from the one in your Anaconda prompt.
If you don't use virtual environments, you should start. To make one, open an Anaconda prompt and do this (changing the name myenv to whatever you like):
conda create -n myenv python=3.7 jupyter matplotlib pandas
Change the version of Python or the other packages too if you want.
When that's finished, switch to that environment:
conda activate myenv
Now do this:
python -m ipykernel install --user --name myenv
This adds a Jupyter kernel for this environment. You only need to do this once, after creating the environment.
Now restart Jupyter notebook or Jupyter lab or whatever. Or install more stuff in this environment if you want. You can just use pip like so:
pip install awesomepackage
You should now see your environment under Kernel > Change kernel, and under New when making a new notebook.
Forgive me if you know all this, but this is the only way I've been able to keep environments straight, and to know exactly where I'm installing stuff. Good luck!
So the solution I've found is that simply using pip install is incorrect.
This link here shows the way it has to be done. By using the command:
!{sys.executable} -m pip install numpy
I am correctly able to import the package and use it.
If anyone could help me understand how this command works that'd be super helpful. This has solved my problem but I don't really know why or how.
I recently downloaded anaconda and added it to the environment variables following the question below:
anaconda - path environment variable in windows.
I added it as
C:\Users\My_User\Anaconda3
The thing is, I've been trying to install some packages using either pip or conda without luck.
For instance:
pip install seaborn
Return the following
Error output
Does somebody know how can I enable package installation either through pip or conda?
I'm very new to executing commands through cmd and couldn't figure out a better way to type my question, sorry about that
Step 1:
Open Anaconda Navigator
navigator
Step 2:
Go to Environments and select All packages, to view the list of all packages installed.
environment packages
Step 3:
Look for seaborn in the Search bar
search bar
Install it and see if that works.
If it doesn't then try creating a new environment and installing the seaborn package there. create new environment
Try
python -m pip install seaborn
You're getting this error because you're running pip from inside of the Python interpreter when you should be running it from the command line. To exit the Python interpreter, press ctrl+d. Then, make sure you have pip installed and in your PATH and you can try again.
I want to import sklearn but there is no module apparently:
ModuleNotFoundError: No module named 'sklearn'
I am using Anaconda and Python 3.6.1; I have checked everywhere but still can't find answers.
When I use the command:
conda install scikit-learn should this not just work?
Where does anaconda install the package?
I was checking the frameworks in my python library and there was nothing about sklearn only numpy and scipy.
Please help, I am new to using python packages especially via anaconda.
You can just use pip for installing packages, even when you are using anaconda:
pip install -U scikit-learn scipy matplotlib
This should work for installing the package.
And for Python 3.x just use pip3:
pip3 install -U scikit-learn scipy matplotlib
Will leave below two options that may help one solve the problem:
Using conda
Using pip
One might want to consider the notes at the end, specially before resorting to the 2nd option.
Option 1
If one wants to install it in the root and one follows the requirements - (Python (>= 2.7 or >= 3.4), NumPy (>= 1.8.2), SciPy (>= 0.13.3).) - the following should solve the problem
conda install scikit-learn
Alternatively, as mentioned here, one can specify the channel as follows
conda install -c anaconda scikit-learn
Let's say that one is working in the environment with the name ML.
Then the following should solve one's problem:
conda install -n ML scikit-learn
# or
conda install -n ML -c anaconda scikit-learn
Option 2
If the above doesn't work, on Anaconda Prompt one can also use pip (here's how to pip install scikit-learn), so the following may help
pip install scikit-learn
However, consider the last note below before proceeding.
Notes:
When using Anaconda, one needs to be aware of the environment that one is working.
Then, in Anaconda Prompt, one needs to run the following
conda $command -n $ENVIRONMENT_NAME $IDE/package/module
$command - Command that one intends to use (consult documentation for general commands)
$ENVIRONMENT NAME - The name of one's environment (if one is working in the root,
conda $command $IDE/package/module is enough)
$IDE/package/module - The name of the IDE or package or module
If one needs to install/update packages, the logic is the same as mentioned in the introduction. If you need more information on Anaconda Packages, check the documentation.
What is the flag -c.
pip doesn't manage dependencies the same way conda does and can, potentially, damage one's installation.
If you are using Ubuntu 18.04 or higher with python3.xxx then try this command
$ sudo apt install python3-sklearn
then try your command. hope it will work
I did the following:
import sys
!{sys.executable} -m pip install sklearn
I've tried a lot of things but finally, including uninstall with the automated tools. So, I've uninstalled manually scikit-learn.
sudo rm -R /home/ubuntu/.local/lib/python3.6/site-packages/sklearn
sudo rm -R /home/ubuntu/.local/lib/python3.6/site-packages/scikit_learn-0.20.0-py3.6.egg-info
And re-install using pip
sudo pip3.6 install -U scikit-learn
Hope that can help someone else!
This happened to me, I tried all the possible solutions with no luck!
Finaly I realized that the problem was with Jupyter notebook environment, not with sklearn!
I solved the problem by re-installing Jupyter at the same environment as sklearn
the command is: conda install -c anaconda ipython. Done...
The other name of sklearn in anaconda is scikit-learn. simply open your anaconda navigator, go to the environments, select your environment, for example tensorflow or whatever you want to work with, search for scikit_learn in the list of uninstalled packages, apply it and then you can import sklearn in your jupyter.
SOLVED:
The above did not help. Then I simply installed sklearn from within Jypyter-lab, even though sklearn 0.0 shows in 'pip list':
!pip install sklearn
import sklearn
What I learned later is that pip installs, in my case, packages in a different folder than Jupyter. This can be seen by executing:
import sys
print(sys.path)
Once from within Jupyter_lab notebook, and once from the command line using 'py notebook.py'.
In my case Jupyter list of paths where subfolders of 'anaconda' whereas Python list where subfolders of c:\users[username]...
On Windows, I had python 3+ version. pip version - 22.3.1
I had installed:
pip install sklearn
But, it seems it is deprecated with scikit-learn.
So, I did:
pip install scikit-learn
And, it worked!!!
Cause
Conda and pip install scikit-learn under ~/anaconda3/envs/$ENV/lib/python3.7/site-packages, however Jupyter notebook looks for the package under ~/anaconda3/lib/python3.7/site-packages.
Therefore, even when the environment is specified to conda, it does not work.
conda install -n $ENV scikit-learn # Does not work
Solution
pip 3 install the package under ~/anaconda3/lib/python3.7/site-packages.
Verify
After pip3, in a Jupyter notebook.
import sklearn
sklearn.__file__
~/anaconda3/lib/python3.7/site-packages/sklearn/init.py'
I had the same problem.
The issue is when we work on multiple anaconda environments, not all packages are installed in all environments.
you can check your conda environment by writing the following code in anaconda prompt:
conda env list
then you can check the packages installed in each environment :
conda list -n NAME_OF_THE_ENVIRONMENT
for me, the environment that I was working with , was missing sklearn, although the package was installed in the other environments.
therefore, I just simply installed sklearn package in that particular environment
conda install -n NAME_OF_THE_ENVIRONMENT scikit-learn
and the issue was resolved
install these ==>> pip install -U scikit-learn scipy matplotlib
if still getting the same error then ,
make sure that your imoprted statment should be correct. i made the mistike while writing ensemble so ,(check spelling)
its
should be >>> from sklearn.ensemble import RandomForestClassifier
I had the same issue as the author, and ran into the issue with and without Anaconda and regardless of Python version. Everyone's environment is different, but after resolving it for myself I think that in some cases it may be due to having multiple version of Python installed. Each installed Python version has its own \Lib\site-packages\ folder which can contain a unique set of modules for that Python version, and where the IDE looks into folder path that doesn't have scikit-learn in it.
One way to try solve the issue: you might clear your system of all other Python versions and their cached/temp files/system variables, and then only have one version of Python installed anywhere. Then install the dependencies Numpy and Scipy, and finally Scikit-learn.
More detailed steps:
Uninstall all Python versions and their launchers (e.g. from Control Panel in Windows) except the one version you want to keep. Delete any old Python version folders in the Python directory --uninstalling doesn't remove all files.
Remove other Python versions from your OS' Environment Variables (both under the system and user variables sections)
Clear temporary files. For example, for Windows, delete all AppData Temp cache files (in C:\Users\YourUserName\AppData\Local\Temp). In addition, you could also do a Windows disk cleanup for other temporary files, and then reboot.
If your IDE supports it, create a new virtual environment in Settings, then set your only installed Python version as the interpreter.
In your IDE, install the dependencies Scipy and Numpy from the module list first, then install Scikit-Learn.
As some others have suggested, the key is making sure your environment is set up correctly where everything points to the correct library folder on your computer where the Sklearn package is located. There are a few ways this can be resolved. My approach was more drastic, but it turns out that I had a very messy Python setup on my system so I had to start fresh.
Using Anaconda-navigator UI environment
When running Anaconda-navigator:
Choose the 'Environments' tab on the left and create a new environment (e.g. ML - see Gonçalo Peres answer above, I made one called 'CourseraML').
Set Python version 3.7 (for Coursera course Applied Machine Learning in Python). Also include R.
Then find modules to install using the 'not installed' drop-down menu item. Search for each module needed in the search bar and select. sklearn is part of scikit-learn. Select it and install (it should find all relevant dependencies). Modules needed for Applied ML course: seaborn, numpy, scikit-learn, pandas, matplotlib
You'll need to restart Jupyter Notebook and reopen your file.
Command line version of above:
conda install -n CourseraML seaborn scikit-learn pandas numpy matplotlib graphviz
Causes
-your jupyter notebook might be importing the sklearn and other libraries from the
another the location(path) than the libraries from conda or pip.
MY Problem
In my case, My jupyter notebook was importing the libraries for snap manager. Since, I install jupyter using the snap instead of other ways.
You can check where other libraries are being imported in jupyter using code:
import cv2 as cv
print(cv.__file__)
Solution
So , I uninstall jupyter notebook and then install notebook using conda.
sudo snap remove jupyter
conda install -c conda-forge notebook
I've been looking everywhere and cannot find a robust explanation.
I'm brand new to Python, coming from R. I had no issues installing packages there but I'm finding it to be rather confusing in Python.
So, I'm using Anaconda and I want to install this package into Python. It mentions using the conda install -c https://conda.anaconda.org/amueller wordcloud command but I have no idea where I'm supposed to run it.
Any advice would be much appreciated.
If you can't find a package with a simple conda search from the command line, run a search on the Anaconda website.
In your case, you'll find that the contributor amueller has his own channel and the package wordcloud is available.
Just run conda install -c amueller wordcloud=1.2.1 to install it.
You might want to create a separate environment using conda create first.
Run it from command line. You can directly install using pip as mentioned in the link. Don't forget to install the pre-requisite packages.
pip install wordcloud
If you are using windows, make sure your environmental path is set so that you can use the pip command directly from windows command prompt. Usually the environmental variable is updated when you install Anaconda distribution.
Conda is just another command which you can use to install packages. Procedure is exactly the same.
You may install packages from interface
