install glmnet in python

Question

Is it possible to install glmnet in python 2 or 3 (windows machine):

Using this:

 conda install glmnet

produces this error:

 packages not found error: ... not available from current channels

Does anyone experience similar problems?

edit: Using pip gave me this error:

failed with error code 1

What have you already tried to resolve this? What operating system are you on, Windows xp, Vista, 7, 8, 8.1, 10, ect? 32 or 64 bit? — Steve Byrne, Apr 12 '18 at 18:21
I am not sure what alternatives I should try, thus the above is all I have to offer so far. I am using Windows 7, I experience the same problem on Win 10. 64 bit both. — Niccola Tartaglia, Apr 13 '18 at 02:02
On one machine, yes. I have 2 and 3. On the other I have only 3 — Niccola Tartaglia, Apr 13 '18 at 02:09

According to the anaconda cloud website glmnet package the available version for mac and Ubuntu users. It's not available yet for Windows users. The only way is to install the r version of it with anaconda r-glmnet.

conda install -c r r-glmnet

The documentation says you should install using either:

conda install -c conda-forge glmnet

or

pip install glmnet

EDIT:

It seems there are multiple "glmnet" packages for python that go by different names. Here is another: https://github.com/conda-forge/r-glmnet-feedstock

To install that one you just do:

conda install -c conda-forge r-glmnet

Either way, the key is to specify which channel you want to install from using the -c flag followed by the channel name (conda-forge), and then the correct name for the package you want

Alternatively, instead of specifying the channel name every time you want to install something, you can add conda-forge to your config with:

conda config --add channels conda-forge

Then you no longer need to use -c and can just install packages with:

conda install r-glmnet

or conda install glmnet

I have tried both for conda, and get the same error. – Niccola Tartaglia Apr 12 '18 at 18:27
for pip I have used the command you suggest, I also tried glmnet_py – Niccola Tartaglia Apr 12 '18 at 18:27
See my edit. I found another glmnet package and not sure which one you actually want. But the key to installing anything from conda forge is to specify the channel name with `-c` – Simon Apr 12 '18 at 18:39
So the other glmnet package works, that is r-glmnet. But for glmnet I still get the same error even after adding the channel forge – Niccola Tartaglia Apr 13 '18 at 01:53
However, I cannot import r-glmnet, due to the dash I am getting a syntax error – Niccola Tartaglia Apr 13 '18 at 01:58
Using this: foobar = __import__("r-glmnet") tells me there is not package called r-glmnet – Niccola Tartaglia Apr 13 '18 at 02:01

It says here that the conda package is only for linux and osx:https://anaconda.org/conda-forge/glmnet – Niccola Tartaglia Apr 13 '18 at 02:34
yeah its possible thats the reason why you cant install it on the Windows platform. Sorry I cant be of much help - Im not familiar with that specific package – Simon Apr 13 '18 at 03:07
I see, thank you so much still for your help though Simon, highly appreciated!! I found a way to do what I was trying to do in scikit learns elastic net, so I think I will just stick to that. – Niccola Tartaglia Apr 14 '18 at 14:33

This is how I succeeded:

You need a fortran compiler. If you're a student (like me), you can get it from intel for free: https://software.intel.com/en-us/qualify-for-free-software/student
Clone the repo for https://pypi.org/project/glmnet/ from https://github.com/civisanalytics/python-glmnet.
Launch the fortran compiler environment in a command prompt
Navigate to the folder where you cloned the repo
Activate the conda environment you want to install glmnet into
Run python setup.py install

The package will now be available as glmnet_python

install glmnet in python
