Doesn't run against the develop branch of datacube-core about datacube-explorer

[jeremyh]

Hi Alex -- thanks for the report.

Support for the next/develop version of the core is in branch next-core.

Our current installations are all in environments that use the stable version of datacube (and the conda install instructions install a stable datacube), so it's the default target at the moment.

Tell me if you run into problems, as it hasn't been tested as thoroughly. I've been rebasing/force-pushing to keep it up to date as a clean set of patches, but changes to core develop could break it again.

Ah, ok @jeremyh. I'll try with that branch.

Got another issue this time:

(Ignore all the dashboard_1 bits)

This may be an issue with out product definition?

That type definition is Python 3.6 syntax. Our Conda installs (and Travis) are all using Python 3.6.

I assume the Python 3.5 you're using is the default on Ubuntu? The difference is quite minor so we could support 3.5 if needed.

[alexgleith]

I just found that.

Datacube supports version 3.5+, so I standardised on that. Never seen the type hints in Python before! Not sure what I think yet ;-)

I think supporting 3.5 would be better.

[alexgleith]

Ok, got it working. I needed to use Python 3.6 and the next-core branch, and also needed to change the generate command to say python3, but it seems happy.

You might like to update the readme in the root to say nohup python3 -m cubedash.generate --all &>> summary-gen.log &

[jeremyh]

Closing. Datacube 1.6 is now released, and we've merged support for it into develop.
