issues

What happened?

I get a FutureWarning when using the .interp method on an xarray.DataArray

The issue is probably related to #6625, #5721 and #6195.

Steps to reproduce

1. conda create -n test xarray scipy
2. conda activate test
3. python -c "import xarray; xarray.DataArray([1., 2.]).interp(dim_0=0.5)"

Expected output

Nothing

Actual output

C:\Miniconda3\envs\test\lib\site-packages\xarray\core\missing.py:562: FutureWarning: Passing method to Int64Index.get_loc is deprecated and will raise in a future version. Use index.get_indexer([item], method=...) instead. imin = index.get_loc(minval, method="nearest") C:\Miniconda3\envs\test\lib\site-packages\xarray\core\missing.py:563: FutureWarning: Passing method to Int64Index.get_loc is deprecated and will raise in a future version. Use index.get_indexer([item], method=...) instead. imax = index.get_loc(maxval, method="nearest")

What did you expect to happen?

I expected no warning

Minimal Complete Verifiable Example

Python import xarray xarray.DataArray([1., 2.]).interp(dim_0=0.5)

MVCE confirmation

• [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
• [X] Complete example — the example is self-contained, including all data and the text of any traceback.
• [X] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
• [X] New issue — a search of GitHub Issues suggests this is not a duplicate.

Anything else we need to know?

No response

Environment

It seems like xarray does not handle unicode file names. The error is present even if the unicode characters appear in the parent path.

MCVE Code Sample

python import xarray as xr import os xr.Dataset().to_netcdf('caesar.nc') os.rename('caesar.nc', 'cæsar.nc') try: xr.load_dataset('cæsar.nc') print('Success') except FileNotFoundError: print('File not found')

Expected Output

'Success'

Actual Output

'File not found'

Problem Description

xarray does not recognize file names with unicode letters

Versions

Hi,

I have a project build on xarray that now fails on travis. It only fails on python 3.7. Have no idea why.

Minimal sample travis.yml that still fails:

language: python python: - "3.7"

install: - python --version - pip --version - pip install --upgrade setuptools numpy - pip install xarray - pip list

script: - python -c "import xarray"

Error message (stack trace):
