Installation problems

[DamienIrving]

I'm trying to install geoviews on a linux machine. I created a new conda environment to try it out and ran the following commands successfully:

conda create --name geoviews jupyter
conda install -c scitools/label/dev -c conda-forge iris cartopy
conda install xarray
conda install -c ioam holoviews

However when trying to install geoviews I found a problem:

conda install -c ioam geoviews
Fetching package metadata: ......
Solving package specifications: ....................................................
Error: Could not find some dependencies for geoviews: cartopy

I can confirm that cartopy is installed:

conda list
...
cartopy                   0.14.2              np111py27_1    conda-forge
...

so I'm not sure what the problem is?

I'll look into this later today. Could you tell me what platform you're on?

[mcmorgan27]

I'm having a similar problem. I'm on ubuntu 16.04 LTS.

[philippjfr]

I think this is down to incomplete instructions. Did you activate the environment after creating it? Could you try doing:

conda create --name geoviews jupyter
source activate geoviews # Previously missing
conda install -c scitools/label/dev -c conda-forge iris cartopy
conda install xarray
conda install -c ioam holoviews geoviews

[philippjfr]

I'll try to dig up an Ubuntu machine to confirm it's actually working, working fine on OSX for me at least.

Did you mean one of these?

geoviews, holoviews

Did you mean one of these?

astropy

You can search for this package on anaconda.org with

anaconda search -t conda cartopy

(and similarly for the other packages)

Okay, just managed to replicate this. I still have no good idea why this happens and will follow up with the conda team, but I was able to solve it by installing them all in one go:

conda create --name geoviews jupyter xarray
source activate geoviews
conda install -c scitools/label/dev -c conda-forge -c ioam holoviews geoviews iris cartopy

[mcmorgan27]

I'll give it a shot. It works on py27 i assume?

Yes, Python 2.7, 3.4 and 3.5 should work.

[mcmorgan27]

all in one go seems to work for me.

Thanks!

Great, if you have any other questions we're also available on Gitter. @DamienIrving let me know if this fixes the issue for you as well. I've already updated the installation instructions in the readme.

[DamienIrving]

@philippjfr Yep, installing it all in one go worked for me too.

Also, thanks for the Gitter link (will ask questions there in future) and congrats on a fantastic library!

Kindly help.

@philippjfr:

conda create --name geoviews jupyter xarray
source activate geoviews
conda install -c scitools/label/dev -c conda-forge -c ioam holoviews geoviews iris cartopy

Doesn't conda go through the channels in order left to right? If so, shouldn't ioam precede conda-forge, to avoid getting the old version of holoviews that's on conda-forge? I would have thought it should be:

conda create --name geoviews jupyter xarray
source activate geoviews
conda install -c ioam -c scitools/label/dev -c conda-forge holoviews geoviews iris cartopy

@khannaum, does that work any better?

[philippjfr]

@jbednar Yes, you're right, I'll fix the README again.

[jbednar]

For what it's worth, here are the versions of each of those packages that are installed on my own system, which I think is what you should see with the above command:

iris                      1.10.dev1                py27_0    scitools/label/dev
geoviews                  1.1.0                    py27_0    ioam
holoviews                 1.6.2                    py27_0    ioam
cartopy                   0.14.2              np110py27_1    conda-forge

[philippjfr]

The latest instructions should work:

conda install -c conda-forge -c ioam holoviews geoviews
# (Optional)
conda install xarray
conda install -c conda-forge iris
