Adding cutsom file format (NetCDF file)

[apprent]

I'm using v0.5, when trying to open a NetCDF file, I got an error:

[Main Instruction]
The following exception occured:

https://docs.xarray.dev/en/stable/user-guide/io.html
https://docs.xarray.dev/en/stable/getting-started-guide/installing.html

==============

It seems that 'netcdf4' and 'h5netcdf' are not in .\pkgs\

How can I find the right version of 'netcdf4' and 'h5netcdf' and install them to .\pkgs\ on my Windows 11 PC?

Thanks!

Dear apprent,

You are right, this dependency is not shipped with the exe of pyDatView.

If you are comfortable with git you can git clone the pydatview repository, install the dependencies and run it locally (similar to the linux or Max installation).

Alternatively, you can install this package in the local Python directory that the setup.exe is creating

• Open a terminal in the python folder created by the setup.exe, for instance:
  C:\Users\XXX\AppData\Local\Programs\pyDatView\Python
• Download the file get-pip.py from: https://pip.pypa.io/en/stable/installation/#get-pip-py and place it in this folder.
• Install pip locally (Note: make sure to always use ./ to use the executable in your current folder, ./python.exe get-pip.py
• Install the packages needed ./python.exe -m pip install netcdf4 --target ../pkgs

(Note I'm not sure if the -target is needed).

If you send me a minimalistic netcdf file that you are using, I can also give it a try.

Dear Branlard,

Thanks for your reply.
I tried the second way and installed netCDF4 in ./pkgs, although there seems to be some dependency errors.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
matplotlib 3.5.2 requires fonttools>=4.22.0, which is not installed.
scipy 1.8.1 requires numpy<1.25.0,>=1.17.3, but you have numpy 2.0.2 which is incompatible.
xarray 2023.2.0 requires packaging>=21.3, but you have packaging 21.2 which is incompatible.
Successfully installed certifi-2024.12.14 cftime-1.6.4.post1 netcdf4-1.7.2 numpy-2.0.2

Now I can open my .nc file (data_0.zip), but as there isn't any variable listed in 1D plot or 2D plot so I can't plot anything.

ps: I tried Panoply the other day and it works fine wiht my .nc file.
