Importing s5a on Windows #28

Open sehHeiden opened 4 years ago

sehHeiden commented 4 years ago

It is not quite simple to install s5a on windows, because it uses h3. After a long time of attempting to install h3 on windows and than s5a.

I wanted to start and try out s5a and found the error:

caused by:

import s5a

Error:

OSError Traceback (most recent call last)

Meaning that the module was not found. I already was so far not to use s5a at all and only use netCDF, but I can't really find the data in that file...

In found the keys in nc.groups['PRODUCT'].variables

But I am unable to find the data so far...

@Meresmata You can take a look here to see how the files are loaded.

Thanks so far....

I found out so far: only import h3 works for me but not the statement from h3 import h3.

Don't have the problem on Linux. (Do you know why? I don't.)

Probably gonna use s5a with my worse linux pc and than pickle the data and than use the pickled data on the stronger windows machine...

So there seem to be problems with H3 and Windows, see https://github.com/uber/h3-py/issues/32. Maybe you find more information about it there.

Another thing you could try, if you want to use your Windows machines is using the Windows-Subsystem für Linux and import your nc files there. I actually never worked with it, but maybe it will solve your problems.
