kandi X-RAY | koala Summary

koala is a Python library. koala has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has high support. You can download it from GitHub.

Koala converts any Excel workbook into a python object that enables on the fly calculation without the need of Excel. Koala parses an Excel workbook and creates a network of all the cells with their dependencies. It is then possible to change any value of a node and recompute all the depending cells.

            I'm afraid that, at the time of this question, Pyspark's randomSplit does not have an equivalent in Koalas yet.

            One trick you can use is to transform the Koalas dataframe into a Spark dataframe, use randomSplit and convert the two subsets to Koalas back again.

            ANSWER

            Answered 2022-Mar-16 at 20:38

            You are making a classic dask mistake of invoking the dask API from within functions that are themselves delayed. The error indicates that things are happening in parallel (which is what dask does!) which are not expected to change during processing. Specifically, a file is clearly being edited by one task while another one is reading it (not sure which).

            What you probably want to do, is use concat on the dataframe pieces and then a single call to to_parquet.

            Note that it seems all of your data is actually held in the client, and you are using from_parquet. This seems like a bad idea, since you are missing out on one of dask's biggest features, to only load data when needed. You should, instead, load your data inside delayed functions or dask dataframe API calls.

            Parallelizing Python code on Azure Databricks
            Asked 2022-Mar-07 at 22:17

            I'm trying to port over some "parallel" Python code to Azure Databricks. The code runs perfectly fine locally, but somehow doesn't on Azure Databricks. The code leverages the multiprocessing library, and more specifically the starmap function.

            The code goes like this:

            ...

            ANSWER

            Answered 2021-Aug-22 at 09:31

            You should stop trying to invent the wheel, and instead start to leverage the built-in capabilities of Azure Databricks. Because Apache Spark (and Databricks) is the distributed system, machine learning on it should be also distributed. There are two approaches to that:

            1. Training algorithm is implemented in the distributed fashion - there is a number of such algorithms packaged into Apache Spark and included into Databricks Runtimes

            2. Use machine learning implementations designed to run on a single node, but train multiple models in parallel - that what typically happens during hyper-parameters optimization. And what is you're trying to do

            Databricks runtime for machine learning includes the Hyperopt library that is designed for the efficient finding of best hyper-parameters without trying all combinations of the parameters, that allows to find them faster. It also include the SparkTrials API that is designed to parallelize computations for single-machine ML models such as scikit-learn. Documentation includes a number of examples of using that library with single-node ML algorithms, that you can use as a base for your work - for example, here is an example for scikit-learn.

            P.S. When you're running the code with multiprocessing, then the code is executed only on the driver node, and the rest of the cluster isn't utilized at all.

            Qt QML ListView sections visible when out of range
            Asked 2022-Mar-04 at 18:37

            I am having trouble bounding my ListView in QML.

            I have taken the example provided by Qt (slightly modified but the exact code from the Qt example has the same issue), and tried to integrate it into my window.

            As you can see in the image below, the ListView is supposed to be the size on the white Rectangle in the middle, yet the section headers are always visible, and the list elements are visible until completely out of the container Rectangle ("Guinea Pig" and "Tiger" are completely visible, although one would expect them to be only half visible)

            I am sure the error is trivial, but i have tried all sorts of anchors and container types, but can't resolve this issue.

            You are simply missing the clip property. That tells the object to prevent child objects from drawing outside of its borders. clip is set to false by default because most of the time its not needed and has a little bit of a performance hit.

            Intersection keeping non-intersecting polygons in sf - R
            Asked 2022-Feb-28 at 08:03

            I'm looking to intersect 2 spatial layers, keeping all the non-intersecting features as well.

            My first layer is the SA2 from NSW, Australia, which look like

            enter image description here

            My second layer is the Areas of Regional Koala Significance (ARKS):

            enter image description here

            When I intersect them, I get part of my desired result, which is subdividing the SA2 by the ARKS.

            enter image description here

            The thing is that I'd like to have also the rest of the SA2 polygons that don't intersect. The desired result would be a map of the SA2, where the intersecting ones would be subdivided by where they intersect to the ARKS layer, and the ones that don't intersect would contain NA. Something like in the next picture but in a single dataset instead of two: enter image description here

            Please consider this approach: Once that you have your intersection, you can remove the intersecting parts with st_difference. That would effectively split the intersecting SA2 in zones based on ARKS, and leave the rest as they are originally. After that, you can rejoin the dataset with dplyr::bind_rows, having the ARKS layer, the SA2 intersected split and the SA2 non-intersected as they are originally:
