PermissionError: [WinError 32] by creating a cutout with era5 [atlite 0.0.4.dev335+gba5daae]

[ced2205]

Hi,
i am running the following code:

CODE

import atlite
import logging
logging.basicConfig(level=logging.INFO)

cutout = atlite.Cutout(path="HH-2019.nc",
                       module="era5",
                       x=slice(8.3, 11.37),
                       y=slice(52.5, 54.32),
                       time=slice("2019-01","2019-12")
                       )

cutout.prepare()

ERROR

the download process is executed as described in the documentation, but then appears the following Error:

Traceback (most recent call last):
  File "D:\Bachelorarbeit\conda\envs\atlite\lib\site-packages\atlite\data.py", line 146, in cutout_prepare
    fd, tmp = mkstemp(suffix=filename, dir=directory)

    fd = _os.open(file, flags, 0o600)

During handling of the above exception, another exception occurred:

Is there any known Bug generating this Error or is my PC causing this Error?

Hi @ced2205 ,

Just to be sure: You installed and are using the v0.2 branch from GitHub, right?

There are no known bugs with windows for the cutout creation, but windows has always been giving us problems .
I'm running your example right now and am trying to reproduce the problem.

Side note: Which package version of pandas are you using (conda list)?

[euronion]

I can reproduce the problem on my machine.

The error seems to be identical to #47 which should have been fixed in data.py, but the changes do not seem to be included in the branch.

We need to check this @coroa @fneum .

For @ced2205
You can specify a tmpdir= in cutout.prepare(tmpdir=...) . The preparation should then work without problems, temporary files however will not be deleted automatically and you will have to cleanup the tmpdir manually.

@euronion

• yes, i am using v0.2

• i am using pandas v1.1.4

thank you! :)

[euronion]

Thanks!

We'll look into it. Probably not in the near future as we are a bit stretched at the moment. Use the workaround for now.

This bug is fixed now. Reopen the issue if you still encounter problems
