Unable to import Normaliz

[Hriday Bharat Thakkar]

I would like to use the Normaliz library to compute Ehrhart polynomials, etc. I have successfully installed Normaliz from their github and Python's IDLE environment detects it but SageMath doesn't seem to be able to detect this installation. 

Can you please advice how I can get SageMath to use Normaliz? So far, I've tried installing Normaliz using two ways: 

1. sage -i normaliz (error: make: *** No rule to make target `all-toolchain'.  Stop.)

2. conda install normaliz libnormaliz from https://doc.sagemath.org/html/en/reference/spkg/normaliz.html

(error for 2. is attached as a screenshot)

Thanks much!

this might need Sage built from source.

2. conda install normaliz libnormaliz from https://doc.sagemath.org/html/en/reference/spkg/normaliz.html

this needs conda channel with Sage (conda-forge). See

https://doc.sagemath.org/html/en/installation/conda.html#sec-installation-conda

Thanks much!

I followed the instructions in https://doc.sagemath.org/html/en/installation/conda.html#sec-installation-conda 

but I'm still unable to install normaliz using 'sage -i normaliz'. Here is the screenshot. Can you please let me know if I've done something incorrectly or if there is some other way to install normaliz/pynormaliz. Thanks!

This is an update. I followed the steps for installation of normaliz via conda. I did the following and was able to install normaliz but when I import normaliz there's an error "Normaliz not found."  It asks me restart my kernel in order to use the updated packages. Can you please advice how I can restart my kernel or what I need to do differently? It seems like conda install normaliz worked. 

Attached is the steps I did:

I thought that normaliz is available as a conda package

you should do these installations at conda prompt,

not at Sage's prompt.

You need to install `pynormaliz` by doing `conda install pynormaliz`.
