Install via conda

[ytsaig]

Hi,

Are there plans to support installation via conda, by creating a conda-forge recipe so that conda install nevergrad -c conda-forge will work?

Hi,
No plan for now, and I would rather avoid having to maintain another way to distribute the code (+ I am not very familiar with conda forge).
Is there any reason why you would not conda install pip and pip install nevergrad?

@jrapin thanks for clarifying. pip and conda don't play well together, and in particular if one wants to create a python package via conda-build (which is a fairly popular package management tool), all packages must have conda recipes, see conda/conda-build#548.

Sorry for the delay in answering, I have been busy on other issues.

As far as I understand I would have to track down dependencies to provide a conda recipe. For the "main" install this means mostly BayesianOptimization, which is OK, and CMA-ES, which seems to have been created but has not been maintained for a year and a half. And I have not looked for other the "benchmark" install dependencies :s
Given the that there is no internal use for it on our side, this has lower priority than other issues I must deal with until more people need it, sorry :(

I would keep the issue open so that anyone needing this as well can let us know, or anyone wanting to take this in charge can do it as well ;)

Hey, sorry for the thread necromancy but I'm also looking to install with conda - is this what is needed; https://github.com/conda-forge/nevergrad-feedstock ?

It's not necromancy, it was not dead yet ;)
That does seem like it, and that would be great news ;)
@oblute thanks for the work, and let me know if you run into an issue (while I did not want to invest time directly in it, I'm happy to help if something is wrong)

@HenryDayHall @jrapin yes, that is what is needed :) you can install with conda now. there should be no issues.
