I want to install the python-igraph package, but I am currently using python 3.6.1 and I don't find any installer for this new version of python. Do you know how can I install python-igraph for this version?
I have tried to install python-igraph for older versions from anaconda cloud but a version problem occurs.
!conda install -c vtraag python-igraph
Fetching package metadata .............
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- python 3.6*
- python-igraph -> python 3.5*
Use "conda info <package>" to see the dependencies for each package.`
I know that python-igraph exists for older python versions, but I don't want to overwrite the current python 3.6 version, so I think I need a new environment to install the older version and be able to use both.
I have already tried to create a new environment for python 3.5:
!conda create -n py35 python=3.5 ipykernel
But after 30min I didn't obtain any response...
I have also followed the same procedure to install a package for python 2.7 (from marufr contributor), but I get the same problem creating an environment for python 2.7.
Note: I am working from Jupyter notebook on Windows (win-64) and using Anaconda.
Update:
Solution found here:
https://medium.com/towards-data-science/environment-management-with-conda-python-2-3-b9961a8a5097
Since there is no python-igraph for python 3.6 yet, I have to use an older version.
First, from Anaconda Prompt, install the nb_conda_kernels package before creating the new environment:
conda install nb_conda_kernels
Then, create the environment where I will work with the older python version:
conda create -n py35 python=3.5 ipykernel
Finally, install the package through the wheel (found here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-igraph)
pip install python_igraph‑0.7.1.post6‑cp35‑none‑win_amd64.whl (You have to this command in the same folder that you donwloaded the wheel!)
There is a Windows installer for igraph‘s Python interface on the Python Package Index. Download the one that is suitable for your Python version (currently there are binary packages for Python 2.6, Python 2.7 and Python 3.2, though it might change in the future). To test the installed package, launch your favourite Python IDE and type the following:
import igraph.test
igraph.test.run_tests()
The above commands run the bundled test cases to ensure that everything is fine with your igraph installation.
Now, you can download 'python_geohash‑0.8.5‑cp36‑cp36m‑win_amd64.whl'.
Use the following command to install:
pip install python_geohash‑0.8.5‑cp36‑cp36m‑win_amd64.whl
Then you can use python-igraph in your Python3.6

I have pygame in pip environment and used it without problem.
But now I switched to conda environment (called tf-gpu) to have TF features also.
As I figured out the most used channel for conda version of pygame is cogsci.
But conda install -c cogsci pygame in terminal causes an error:
It seems there is a version incompatibility.
I then downloaded the original tar.bz2 file from conda, and tried conda install --offline C:\...(file path)
It downloaded and recognized by interpreter(python 3.8.8, conda('tf_gp' env)).
Then Pyhton imported pygame but error of there is no module "from python.base import *" proceeded it.(as it is in the __init__ file of package)
Are these problem due to old version of pygame? I tried other channels in anaconda but unsuccessful(also they were older).
And also i can not downgrade python because of many packages' prerequisites.
I also tried installing via pip(in that conda promp), but it said that the requirment has been satisfied(as i previoisly used pygame in pip env(python 3.8.2).
Is there any new conda version of pygame?
Should i remove previous pygame in pip and try pip install again in conda env?
Or is it possible to modify main package source code(old file)?
This issue usually comes in when you are running many versions of python and pygame together which causes some incompatibility. Another problem which may occur is that anaconda environment stop recognising the pygame as it can’t locate it.
My suggestion is that uninstall all the older versions of python and pygame and install the latest ones.
Or else you may shift to Visual studio code for better experience and lesser problems.
Thanks,
The problem was solved by uninstalling other python version that I had(3.6). and using pip version of pygame(which did not work when two python versions (3.6, 3.8) were on my system.)
I created virtual environment for python 3.4 version.I cant able to use pip from my network. I cant able to download files even. So i created virtual environment and started to install packages using conda install.
When i was using this command conda install -c syllabs_admin justext, i'm getting notification from my server like:
The following packages will be SUPERSEDED by a higher-priority channel:
python pkgs/free::python-3.4.5-0 --> pkgs/main::python-2.7.17-h9bab390_0
Can someone actually help me how to install this justext package for my python version 3.4 using conda install?
Unfortunately, no. There is no way that you can use conda install with any public channel to install justext and your python version. Checking the search function on anaconda.org, there are only two channels that provide justext:
moustik / justext 2.2.0
syllabs_admin / justext 2.2.0
Unfortunately, both have only python 2.7 packaged versions of the module.
you should try to fix your networking issues instead. It sounds really werid that conda install would be working while you claim to not be able to even download any files. Please talk to your IT department or Sys Admin about it or ask another question posting the errors you are getting when using pip install or wget https://files.pythonhosted.org/packages/6c/5f/c7b909b4b864ebcacfac23ce2f6f01a50c53628787cc14b3c06f79464cab/jusText-2.2.0-py2.py3-none-any.whl
I am working with Anaconda with python 2.7. In order to do algorithmic trading I wanted to install 'zipline' package using conda giving command as
conda install -c Quantopian Zipline
from Anaconda prompt. After 'Solving environment' message, I got 'Package Plan' which contains packages which will be installed, removed, updated and downgraded. I was astonished to see that it will remove 'anaconda: 5.2.0-py27_3' and downgrade
networkx: 2.1-py27_0 to 1.11-py27_1;
numpy: 1.14.3-py27h911edcf_1 to 1.11.3-py27hc42714f_10;
numpy-base: 1.14.3-py27h917549b_1 to 1.11.3-py27h2753ae9_10;
pandas: 0.23.0-py27h39f3610_0 to 0.22.0-py27hc56fc5f_0.
I canceled the installation.
I have a couple of question here.
Why at all it is necessary for any package installation to remove package 'Anaconda' and downgrade packages like 'numpy', 'pandas' etc.?
Will this action not jeopardize my other python activities?
Shall I go ahead or restrain from installing the packages like this?
Zipline doesn't currently support the latest versions of packages like panda, numpy etc. which causes the messages above.
Well, yes it could make trouble, especially if your other python activities need the latest version of those packages.
Please don't go ahead with the installation like this. I'll explain the best available solution below.
Solution:
Create an environment for Zipline. Let's say (for convenience only) Zipline supports Python 3.5 but you have only installed Python 2.7 on your machine.
So you can create a sandbox-like conda-environment for Python 3.5. It's very straight forward, just use the following commands:
$ conda create -n env_zipline python=3.5
After your isolated environment called env_zipline was created, you have to activated it by using the following command:
$ activate env_zipline
You can install Zipline now by running
(env_zipline)$ conda install -c Quantopian zipline
When you finished your work with zipline you can deactivate the environment for zipline by using the following command:
(env_zipline)$ deactivate
Hope it helps. If your need further information you can check the more detailed documentation of zipline (the steps above are included):

My question is thoroughly based on this question. The big difference is I'm focusing on windows here. The answers/question provided there were for unix distributions.
I've ran Python 2.x for quite a while and have used pip with no problems.
Now I've installed python 3 but when I open the cmd prompt and pip install somemodule it tries to install it for python 2. How can I deal with this situation ?
Both Python's were installed with the Anaconda distribution so I believe both of them come with pip installed. Note: This info come from this question
EDIT:
Found this answer which addresses that issue.
But now when I try to run the command
pip3.5 install pymssql
or
pip-3.5 install pymssql
I get the error pip3.5 is an unknown command.
If I open cmd and type python I receive:
Python 3.5.1 Anaconda 4.0.0
so it shouldn't be a version problem
You will want to make sure you have the correct Anaconda environment activated, which it looks like you have in this case.
conda env list # Display the list of conda environments
In the Windows Command Prompt you should just need to use:
activate py35 # Or whatever your Python 3.5 environment is called. (Mine is root)
pip install pymssql
Instead of pip-3.5.
To install it in another environment (mine is called py27):
activate py27
pip install pymssql
I successfully used this command in both my Python 2.7 and 3.5 Anaconda environments.
To go back to your primary environment (root), just type activate without an environment name after it
I am using the Anaconda python distribution for 64 bit, windows

I am now trying to do some genetic search, and tried to install Pyevolve
http://pyevolve.sourceforge.net/
Unfortunately it crapped out saying
"Python 2.6 not found in registry"
I do have Python 2.7.6 through Anaconda. Any way around the issue? Thanks.
I managed it using binstar:
Look for available packages: binstar search -t conda pyevolve (two packages found OpenMDAO/pyevolve and greole/pyevolve)
Ask for details of chosen package: binstar show openmdao/pyevolve (install link given)
Install package: conda install --channel https://conda.anaconda.org/OpenMDAO pyevolve
Enjoy working with pyevolve!
My system: Win8, 64-bit, Python 2.7.8, Anaconda 2.1.0 (32-bit).
Anaconda suggests using "conda" for package management. There are some package not available in its repository. You can try command below:
conda search Pyevolve
Pyevolve seems depend on Python 2.6, you can try conda to setup a new environment in 2.6 version.
