I want to use KDE Cantor with python and packages from Anaconda.
I am running Linux Mint 20 XFCE, I have the cantor and cantor-backend-python3 packages installed, as well as miniconda.
Is there a way I can make Cantor use my conda environment, or import packages from conda in Cantor?
I am not sure what to change in the cantor python settings. I have also tried from the command line with the desired environment. If I run python3 then >>> import a_conda_package, the package is imported. But (base) $ cantor then import a_conda_package is not found.
Thank you.

I recently used the following command to update my jupyter packages conda update --all and from then on my visualization libraries wont import(matplotlib and seaborn). I used conda install <pkg> even then it wouldnt. So I reinstalled anaconda3 but same problem persists...
I tried to view sys.executable and found that it was not referencing my python lib in anaconda but in python click here
'c:\\python38\\python.exe' So i used pip3 install matplotlib and matplotlib worked. I want my jupyter to reference to its own lib stack as I cannot install all libraries in python. I want the jupyter to read packages from this path : C:\Users\princ\anaconda3\Lib\site-packages because all anaconda libraries are there. How do I do it? Help me please. The problem is jupyter is referencing python package folder and not pre installed packages in anaconda
SYS.PATH:
'c:\\python38\\python38.zip',
'c:\\python38\\DLLs',
'c:\\python38\\lib',
'c:\\python38',
'',
'C:\\Users\\princ\\AppData\\Roaming\\Python\\Python38\\site-packages',
'c:\\python38\\lib\\site-packages',
'c:\\python38\\lib\\site-packages\\win32',
'c:\\python38\\lib\\site-packages\\win32\\lib',
'c:\\python38\\lib\\site-packages\\Pythonwin',
'c:\\python38\\lib\\site-packages\\IPython\\extensions',
'C:\\Users\\princ\\.ipython']
jupyter kernelspec list
python3 c:\python38\share\jupyter\kernels\python3
Did you tried running pip using directly the python executable with
python.exe -m pip install <pkg>
I don't know if there is a similar way to do it with conda
For scientific computing use cases, it is amazing that Anaconda distribution has MKL optimization for libraries like numpy, scipy etc.
I am wondering what if I use Miniconda instead, and install numpy via conda command, does it ship the same benefits of MLK optimization as what Anaconda does ?
Yes, it ship the same benefits of MLK optimization as what Anaconda does.
These Miniconda installers contain the conda package manager and Python. Once Miniconda is installed, you can use the conda command to install any other packages and create environments, etc.
For example:
$ conda install numpy
...
$ conda create -n py3k anaconda python=3
...
Note: If you already have Miniconda or Anaconda installed, and you just want to upgrade, you should not use the installer. Just use conda update.
For instance:
$ conda update conda
will update conda.
Yes, it is exactly the same package as would come with the Anaconda installer.
Note that you can also install NumPy from the conda-forge channel, if you wanted to use OpenBLAS instead of MKL.
I created a conda env and installed tensorflow 1.4
pip install tensorflow==1.4
This installed, and from within the environment, when i type
import tensorflow as tf
tf.__version__
it prints '1.4.0'
Now, i open jupyter notebook from the same environment, and when i type the same in the notebook, it gives me 1.10.0
How is this possible? Jupyter notebook should take the same libraries within which it is running. How does it have a different version of tensorflow
And btw I'm concerned with this because i wanna use 1.4.0 in my notebook
These are the questions I ask myself in situations like this, and they usually resolve my issue:
Was the kernel of my notebook running while I pipped? Shut down and restart.
Are pip and conda sharing PATH, et cetera? I don't take it for granted that my pip is modifying my conda env. You can check with these commands.
Your conda env is created, but is it active? You list created envs with these, and you can activate/deactivate with these.
Besides checking all of these, where am I launching jupyter from? I like to install jupyter with a simply pip install jupyter and that could add jupyter to the command line globally. Anaconda navigator/command line reliably launches the jupyter that lives in your Anaconda distribution.
To add to Charles Landau:
You likely installed tensorflow in parallel with pip and with conda.
Within your env, just check with pip list tensorflow and conda list tensorflow. Most likely you will see two different versions.
To be consistent do:
pip unistall tensorflow to keep only one.
I created a new conda environment as follows
conda create -n NAME python=3.5
Added edit, of course activate the environment like so
activate NAME
Installed these libraries all at once
conda install numpy scipy pandas scikit-learn jupyter matplotlib
relevant libary versions that conda installed
when importing pandas ge
ImportError: Missing required dependencies ['numpy']
Can anyone replicate this installation of env on windows? I am thinking one of the files version are causing this and cannot find a solution, barring an externality.
Have uninstalled and installed pandas, numpy, etc all libraries, have also tried installing with pip even, nothing is working. Have even created another environment from scratch same error is occurring.
Conda should have installed a number of libraries when you build python 3.5 in the new environment. If you run "conda list" in the command line of the newly built environment it will show the packages you have by default. Try to build the environment with "conda create -n py35 python=3.5 anaconda" so it uses the anaconda python and will auto install packages.
I am using python 2.7 in Ubuntu and recently updated tensorflow 0.12.1.
I installed jupyter today for my sample code of tf and I need to use matplotlib. It does not find module name matplotlib and ipython in tensorflow has same error.
1. How can I set path in virtualenv or ipython or jupyter?
After activate tensorflow, I need to use jupyter notebook.
This below in the script for error does not work.
import sys
sys.path.append('my/path/to/module/folder')
import module-of-interest
2. other information: My environments are below.
mickyefromsd#DEKSTOP~$source ~/tensorflow/bin/activate
When I find matplotlib by python script under TF condition and before TF activation, it has below;
/usr/lib/python2.7/dist-packages/matplotlib/
When I type 'which ipython', it has below (not by /usr/bin/ipython) ;
/home/mickeyfromd/tensorflow/bin/ipython
Btw, /tensorflow/lib/python2.7/site-packages/ it has ipython and jupyter.
(not in the same path of matplotlib)
3. My ipython under TF cannot find my existing matplotlib.
(tensorflow) mickeyfromd#DK-DESKTOP:~$ ipython
Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
In [1]: import matplotlib ImportError: No module named matplotlib
4. I wanted to setup virtualenv, so I just run this
I followed this site. site:http://help.pythonanywhere.com/pages/IPythonNotebookVirtualenvs
(tensorflow) mickeyfromd#ipython kernelspec install-self --user
.....
Installed kernelspec python2 in /home/mickeyfromd/.local/share/jupyter/kernels/python2
(tensorflow) mickeyfromd#DK-DESKTOP:~$
I cannot move the the folder (in the second step)
How can I make ipython to have path for Matplotlib?
That import error is due to change in environment of the jupyter notebook. You might have installed the packages in one environment and you are running the jupyter notebook in another environment.
I have got two environments (envs) in my Anaconda folder ( I have Anaconda3 folder to be specific ).
(windows key+cmd ) -> open the windows command prompt run as administrator.
Activate (name of the environment) -> eg.: activate tensorflow-gpu
Start installing packages using conda install
Note: For each environment you need to install all the packages you want to use, separately using the same process. This solution is for windows users, might work for linux users not sure though.
Additionally to make sure your conda environment is up to date run:
conda update conda
conda update anaconda
