QUESTION
Dears, I need to create a xarray.datarray with the names of the dimensions equal to the names of the coordinates, however, I am not succeeding. Here is the code for reproduction:
...ANSWER
Answered 2021-Sep-20 at 18:44The short answer is you can't use .sel to select individual elements within multi-dimensional coordinates.
See this question which goes into some possible options. If you have multi-dimensional coordinates lat/lon, it is not at all guaranteed that da.sel(lon=..., lat=...) will return a unique or correct result (note that xarray isn't designed to treat lat/lon as a special geospatial coordinate), so da.sel is not intended for this use case.
You either need to translate your intended (lon, lat) pair into (x, y) space, or mask the data with t2.where((abs(t2.lon - lon) < tol) & (abs(t2.lat - lat) < tol), drop=True) or something of the like.
See the xarray docs on working with MultiDimensional Coordinates for more info.
QUESTION
I am trying to pull back all the data from my sql statement but I am only able to pull back the first row data in the first put statement. So what I am trying to do is do a for loop through the $data variable. The for loop won't run because it says that the variable is an array.
...ANSWER
Answered 2021-Jun-02 at 19:05The problem is when you do foreach value $data; since the data variable is an array, you can't read it as a simple value. To print the keys and values in the array, do this:

QUESTION
I'm using Apache Parquet Hadoop - ParquetRecordWriter with MapReduce and hit ParquetEncodingException: writing empty page. Despite I found, that this is happening in ColumnWriterBase when the valueCount is 0, I don't undrestand the real reason why this property is 0, why it has something with Endoding and how can such state happened? Any idea? Thanks for any tip.
ANSWER
Answered 2020-May-19 at 08:39I think the problem is with the start/end calls. One issue is that startMessage() and endMessage() are invoked twice, once in write(MyData) and again in writeData(MyData).
I would suggest using the ValidatingRecordConsumer as a wrapper for the recordConsumer you use. This way you may get more meaningful exceptions if something is wrong with the record serialization.

Answered 2020-Mar-23 at 10:15In terms of doing this in a more 'efficient' way, there are two things to point out.
1) You're allowed to do arithmetic operations directly on xarray objects eg.

Install datarray
You can use datarray like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
