Is Windows (no WSL) supported?

[matteodefelice]

I think the answer is "no", but I just want to be sure, perhaps someone had success in using PyPSA-EUR on windows.
I can compile the tutorial (electricity) but if I try something larger I get:

1. A ProtectedOutputException because the files in data\bundle are read-only. After removing the read-only...
2. It says there are incomplete files that are actually complete:

IncompleteFilesException:
The files below seem to be incomplete. If you are sure that certain files are not incomplete, mark them as complete with

    snakemake --cleanup-metadata <filenames>

To re-generate the files rerun your command with the --rerun-incomplete flag.
Incomplete files:
cutouts/europe-2013-sarah.nc
cutouts/europe-2013-era5.nc
resources/load.csv
results/config.yaml

I cannot clean up the metadata because snakemake says that the metadata is not present.

[fneum]

We don't really test it without WSL.

Could you, nonetheless, try the following:

• Just remove the .snakemake folder. This will clear the metadata the hard way.
• Ensure the cutouts match the size they have on zenodo: https://zenodo.org/records/6382570
• In rules/retrieve.smk, you can remove the write-protection: protected(...) if that causes trouble.

Thank you, deleting the .snakemake folder unblocked. I could continue the building but I got an error after a few minutes:

I have switched to WSL to compile everything and then I perform the solve step on Windows (I don't have Gurobi for Linux).

UPDATE: I get the same error on WSL (using cbc), so it's not Windows-specific
I get this error:

(BTW, I am running the version 0.9.0)

Ah, in your config, set lines: max_extension: 20000. The transmission loss approximation, which is now the default, requires an upper limit to the expansion of individual lines.

Fixed in 647a988

[matteodefelice]

Added it to my config file, deleted the folder .snakemake and pulled the latest commit but I still get the same error. What am I missing?

[euronion]

Have you tried re-creating the networks used as input for the rule?

[matteodefelice]

@euronion how should I do that?

[euronion]

@matteodefelice You'd have to rerun the execution graph including the rule(s) which use the config entry, i.e. for lines: max_extension: 20000 the rule prepare_network. Since it's the rule directly preceeding solve_network in the DAG, the simplest thing is to just delete resources/networks/elec_s_128_ec_lv1.5_.nc and run the workflow again.

@fneum max_extensions is not listed under params for rule prepare_network, is that intentional?

[fneum]

Closing since it seems to be stale. But reopen if issue persists.
