QUESTION
I have a grib file and I am trying to format the date for my title, but I don't know the best way to accomplish this. The date format in the dataset is 1970-01-01. I would like it to display in the title as 01-01-1970. I get the following error when I run the code, "'str' object has no attribute 'strftime'.

I am working with .tif images. I try to read a .tif image in order to access it later on pixel level and read some values. The error that I get when using Pillow is this:
...ANSWER
Answered 2022-Mar-13 at 14:09Your image is 4-channels of 32-bits each. PIL doesn’t support such images - see Available Modes here.
I would suggest tifffile
or OpenCV’s cv2.imread(…, cv2.IMREAD_UNCHANGED)
QUESTION
I am attempting to plot fields from a GRIB2 file of GFS model data (example file: https://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.20220202/12/atmos/gfs.t12z.pgrb2.0p25.f006 ). Normally I would just use PyGRIB and I'd have this problem solved yesterday, but I am on Windows (because it's what my employer uses, so I'm stuck with it and have to make this work on a Windows environment) and Windows and PyGRIB don't play nice. I am able to open the GRIB2 file and even plot variables over the entire domain using GDAL. The only problem is I need a way to get an array of the latitude and longitude values at each grid point (similar to in PyGRIB doing .latlons() on a GRIB message) so I can plot a subset of the domain.
Basically, I'm trying to replicate what is being done in this video, and need the data (got it using dataset.GetRasterBand(269).ReadAsArray()), then the lat/lon information.
I also tried using xarray, but Windows doesn't play nice with xarray either.
...ANSWER
Answered 2022-Feb-03 at 00:40Given your comfort with PyGRIB, I'd say the solution is to use Conda and install it on Windows. You can use conda-forge's miniforge to install conda. Then, however you get Conda, install pygrib with:

QUESTION
I want to make elements in row in one layout and a lot of layouts will be in GroupBox, it must be like this.
I try to release this
...ANSWER
Answered 2021-Dec-03 at 10:55The layout you're showing is not a form layout, it could be a grid layout, but it actually seems more like a QTableView (or QTableWidget) or even a QTreeView (if those small arrows on the left are used to expand elements). Using nested layouts in this case might not be a good solution, as each layout would be independent from the others, with the result that the widgets might not be properly aligned. This small arrows for expand element in that case a QTreeView with a QStandardItemModel or a QTreeWidget might help, then use setItemWidget() to add buttons. – musicamante
QUESTION
I am trying to use the Grib.Api package to read the content of a .grib file. The code I'm using is picked up from the gitHub code of the library (https://github.com/GribApiDotNet/GribApi.NET):

Answered 2021-Dec-02 at 18:40I'm nearly certain it's because you're trying to use it in a .net core or .net 5+ project; create a .net framework based one instead.. I had a similar issue with this exact lib, managed to find the two projects in my scratch folder:
I didn't dig any further into the .net core incompatibilities, as I only needed it for a decode of one file, so just made a NETFW472 project..
