[pipx] Cannot determine package name from spec

I am trying to

pipx install 'git+https://github.com/pmav99/inspectds.git'

but I get

Load coordinates by default

I.e. instead of this:

Dimensions:     (step: 73, latitude: 285, longitude: 313)
Coordinates:
    number      int64 ...
    time        datetime64[ns] ...
  * step        (step) timedelta64[ns] 00:00:00 01:00:00 ... 3 days 00:00:00
    surface     float64 ...
  * latitude    (latitude) float64 74.97 74.9 74.83 74.76 ... 55.15 55.08 55.01
  * longitude   (longitude) float64 -29.95 -29.88 -29.81 ... -8.085 -8.015
    valid_time  (step) datetime64[ns] ...

display this:

Dimensions:     (step: 73, latitude: 285, longitude: 313)
Coordinates:
    number      int64 0
    time        datetime64[ns] 2018-10-01

Fail Graciously when inspecting a GRIB and GRIB support is not available

We now throw an exception similar to this:


inspectds /home/user/Downloads/20220725.00.tropical_cyclone.grib

AttributeError: GRIB

We should suggest installing cfgrib instead.

Use Annotated

The new typer API suggests using Annotated. We should switch to that.

Allow dropping variables

There are netcdf files that are not compatible with xarray (source). We should either allow the user to drop the problematic variables or automatically detect them and drop them.

Inspect remote files

For example:

$ inspectds http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/ncep.reanalysis/surface/air.sig995.2020.nc

Should output something like this:

<xarray.Dataset> Size: 62MB
