Installing from conda is a total turkey

valeriupredoi commented 4 years ago

conda install esmvaltool -c esmvalgroup -c conda-forge

results in successive failures of conda to solve the environment and piling up memory consumption in the process (on my puny 4GB RAM machine the conda python process reached 3GB and went straight to swap twice, forcing me to restart the whole machine twice). I am aware this is partly conda's fault for trying to be something that'll never be but it's also our fault for not optimizing the package; we need to fix this since people are trying to install it this way and not from source and giving up in the process (one case reported to me in the last 24h); I will look into this tomorrow but I ask @bouweandela and @bjoernbroetz to have a think too :beer:

bouweandela commented 4 years ago

Maybe you could open an issue about this with conda? https://github.com/conda/conda/issues

It looks like similar issues have been reported before, e.g. https://github.com/conda/conda/issues/7787, https://github.com/conda/conda/issues/8650

My installation finished:

tiptop, mate, tiptop :rofl:

valeriupredoi commented 4 years ago

I can't see your comment about the env solving quickly w/o ncl - did you remove it?

bouweandela commented 4 years ago

Sorry, yes, because it was confusing, e.g. conda create -n test -c esmvalgroup -c conda-forge esmvaltool-r imagemagick ncl takes about a minute to resolve and 1.2 GB or RAM and installs the exact same packages as conda create -n test -c esmvalgroup -c conda-forge esmvaltool, which takes an hour and needs 7GB RAM.

valeriupredoi commented 4 years ago

what does -r do?

valeriupredoi commented 4 years ago

OK @bouweandela some progress twoards understanding this:

conda env create ... is actually very quick and only taking 1.5G which is normal; why is conda create ... so bulky is puzzling;

installing just esmvalcore fails:

 -> it would be very useful if you could create an up to date esmvalcore package so we can see if the issues with installing `esmvaltool` stem from conflicts with `esmvalcore` deps - usually conda decides it can still solve an env that is otherwise insolvable (if fewer deps were in the list) and goes on forever with no avail

valeriupredoi commented 4 years ago

@bouweandela can you pls produce a new esmvalcore package, ship it to esmvalgroup, change the install instructions on the page and let me know when you've done that, please mate? I will test the installation from conda right away that's done, I suspect our conda woes will be fixed by doing this :beer:

bouweandela commented 4 years ago

what does -r do?

It installs only the esmvaltool-r subpackage, as described in our installation instructions.

we need to change the instructions at https://anaconda.org/ESMValGroup/esmvalcore

I've done that a few times already, but these instructions get overwritten with the default every time I upload a new package, so I'm not going to do that anymore. I reckon people should just use the installation instructions from our documentation.

OK we really need a new esmvalcore package, am hitting this (proj-related issue that we solved a month or so ago):

Could you please share all commands you ran to create this environment, so I can try to reproduce your issue?

valeriupredoi commented 4 years ago

conda install -c conda-forge -c esmvalgroup esmvalcore
esmvaltool --help

am trying it on Jasmin as well at the mo, will report back :beer:

bouweandela commented 4 years ago

Could you also share the commands you used to create the environment that you're installing into?

valeriupredoi commented 4 years ago

no other commands man, installing in the conda (base) - ideally when a user does conda install ... they should not create any environment prior to :beer:

bouweandela commented 4 years ago

I just downloaded conda (version 4.8.3) and ran

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh
# chose ~/conda-test as an installation directory
. conda-test/etc/profile.d/conda.sh
conda activate base
conda install -c conda-forge -c esmvalgroup esmvalcore
esmvaltool --help

and everything worked perfectly. What version of conda are you using? Can you provide a link for downloading from the archive: https://repo.anaconda.com/miniconda/

bouweandela commented 4 years ago

Or maybe a link to a docker container that runs the conda version that has the problem?

valeriupredoi commented 4 years ago

here are the traceback steps Monsieur Le Bouwe:

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh
conda install -c conda-forge -c esmvalgroup esmvalcore

note that I accepted conda to prepend the installation and activate base right away, equivalent to the snippet in .bashrc:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/valeriu/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/home/valeriu/miniconda3/etc/profile.d/conda.sh" ]; then
        . "/home/valeriu/miniconda3/etc/profile.d/conda.sh"
    else
        export PATH="/home/valeriu/miniconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

and for the big finale:

valeriupredoi commented 4 years ago

Massive hint: when you uninstall esmvalcore and install esmf(since it'll be removed with the uninstall of esmvalcore) that one is compiled correctly against mpi with mpich:

(base) valeriu@valeriu:~$ conda list esmf
# packages in environment at /home/valeriu/miniconda3:
#
# Name                    Version                   Build  Channel
esmf                      8.0.1           mpi_mpich_h213fab7_100    conda-forge

right after this if you re-install esmvalcore, then it'll work nicely. You need to check that the requirement for esmf in the conda recipe for esmvalcore is set correctly for mpi with mpich :beer:

valeriupredoi commented 4 years ago

strange, I have repeated the install steps on Jasmin and all works fine there out the box with

(base) [valeriu@jasmin-sci2 ~]$ conda list esmf
# packages in environment at /home/users/valeriu/miniconda3:
#
# Name                    Version                   Build  Channel
esmf                      8.0.1           nompi_hbeb3ca6_0    conda-forge

I still reckon it's best to run a few installation tests on different OS's after the package gets built. It might be that my OS is old (Ubuntu 14 is ancient, 6 years old) but even so it shouldn't matter

jasmin's OS:

It also works fine on my laptop and on CircleCI, so I wouldn't be suprised if it's somehow related to your OS or user profile.

valeriupredoi commented 4 years ago

what are you running on your laptop - if it's a Debian-based OS then am OK to call this solved (well, the installation of esmvalcore that is, for now, I am still struggling with esmvaltool) :beer:

bouweandela commented 4 years ago

I'm running ubuntu 20.04. Trying to reproduce your issue now with ubuntu 14.04.

bouweandela commented 4 years ago

Yes, I managed to reproduce it!

valeriupredoi commented 4 years ago

excellent! did you build a container with that ye olde OS? Got good news - I managed to install esmvaltool on Jasmin straight from conda (well, it's installing now, but the env solving lasted about a smoke's time :grin: ) - this was after I've installed esmvalcore from conda so it may be that either this is a workaround or conda fixed their troubles (I'll uninstall them both and try installing esmvaltool from scratch)

valeriupredoi commented 4 years ago

I'm running ubuntu 20.04. Trying to reproduce your issue now with ubuntu 14.04.

way to go updated OS, man! What's that one called, Flying Dutchman? :grin:

bouweandela commented 4 years ago

Indeed I did

docker pull ubuntu:14.04
docker run -it ubuntu:14.04

and that reproduced the problem. I also found lots of other people having the same issue: https://github.com/pytorch/pytorch/issues/2575#issuecomment-523667875

It looks like the publicly available Ubuntu 14.04 is no longer maintained: https://ubuntu.com/about/release-cycle, so maybe now would be a good time to upgrade?

valeriupredoi commented 4 years ago

aw mate, 14.04 hasn't been supported since April last year :grin: but you know, updating an OS that is 11 version increments old is probably suicidal. Nah, it's fine, we should log this somewhere and if some oldtimer like me complains in a future issue we will know what he problem is

In order to install the Conda package, you will need both conda and Julia pre-installed, this is because Julia cannot be installed from conda.

you reckon I don't know that? :grin: I am not happy with the conda installation to fail because of that - we need to make it install and throw a big warning at the end saying this and that Julia but not to fail altogether; this is in line with that R diagnostic test that is still failing if R is not installed (bump: approve that PR, mate) :beer:

Maybe you could open a pull request to improve the error message?

valeriupredoi commented 4 years ago

oh I will and it'll contain a few changes:

you do realize that just by pointing the user to the Julia download page will not cut the mustard - that page is cryptic to start with and the actual installation procedures specific for a conda env to be correctly built are not there;
can we default the installation from conda (conda install -c conda-forge -c esmvalgroup esmvaltool) to the installation without needing Julia? That would be absolutely awesome because it'll be very straightforward

valeriupredoi commented 4 years ago

OK I managed to catch this loose tiger that conda pretends to be: if you want to install esmvaltool from conda you will end up spending the good part of your day looking at that spindle spin and not solve the environment - if you install esmvalcore first, esmvaltool env will be solved in 3min and chuck at most 2G of mem. I will make a PR with updated instructions including how to install and softlink julia before installing :beer:

No, I think not, because then it will not work if people try to run a Julia diagnostic. For advanced users that know they do not want Julia diagnostics, we have the subpackages, e.g. conda install esmvaltool-python esmvaltool-r esmvaltool-ncl will get you esmvaltool without Julia. Maybe we could make it possible to install the julia dependencies later, once we have the new command line interface. Or we could try to change the script so it installs Julia as well as the Julia dependencies, but I'm afraid that might be bit error prone.

valeriupredoi commented 4 years ago

OK let's keep it this way then, I am happier now that we are actually telling the user how to install Julia and make the executable available. I will try today or tomorrow see if we can get Julia back inside the conda environment, although doubt much has changes in the meantime :beer:

closing this since it works now, beware a reopen :grin:

valeriupredoi commented 4 years ago

ah the dreaded reopen :grin: As per the instructions installing from conda via simple conda invocation gets stuck in conflict zone:

conda install -c esmvalgroup -c conda-forge esmvalcore

Solving environment: failed with initial frozen solve. Retrying with flexible solve.

on an anaconda install, in a base environment:

valeriu@valeriu-PORTEGE-Z30-C:~/ESMValCore$ conda -V
conda 4.8.3
valeriu@valeriu-PORTEGE-Z30-C:~/ESMValCore$ python -V
Python 3.8.3

I am adding the conda install test in #700 now and we can see this distributed to both Linux and OSX for different Python versions :beer:

valeriupredoi commented 4 years ago

too much fluff here, closing this and reopening a new, more precise one :beer:

ESMValGroup / ESMValCore

Installing from conda is a total turkey #660
