QUESTION
I have a dataframe where one column is ; separated strings, e.g. "str1;str2;str3;str4", I also have another static list "strx;stry;strz", the goal is to split the column string value and check if the split array has any intersection with the static list, and keep that row
I tried
...ANSWER
Answered 2021-Jun-15 at 20:34It seems you're mixing up Spark's split method for Columns with Scala's split for Strings. Please see example below for how the two different split methods are used. Method array_intersect is for intersecting the split Array column with the split element-filter string.
QUESTION
I need to find the intersection of two arrays and print out the number of elements in the intersection of the two arrays. I must also account for any duplicate elements in both the arrays. So, I decide to take care of the duplicate elements by converting the two arrays into sets and then take the intersection of both the sets. However, I encounter a segmentation fault when I run my code. I'm not sure where this occurs, any way to fix this?

You need a vector with some space. Change vector v; to vector v(n+m);

I'm developing a simple navigator with mapbox API for Android.
I'm creating some routes using https://docs.mapbox.com/playground/directions/ playground and i would like to use the generated JSON to generate a DirectionsRoute object.
So i call DirectionsRoute.fromJson() but when i do it, the application crashes with this error:

Answered 2021-Jun-15 at 08:12The response from the mapbox API is not DirectionsRoute. It is DirectionsResponse, a structure that looks like this:
QUESTION
In ElasticSearch, what's the rough implementation for an AND-style boolean query where the fields are term types? Does ElasticSearch run filter queries separately on each of the field, and then find their intersections?
For example, if I have something like
...ANSWER
Answered 2021-Jun-15 at 03:14That kind of queries are extremely fast. Moreover, you should use bool/filter instead of bool/must as that will leverage filter caches and reuse existing filters to run the subsequent queries even faster.
You should go through this article which explains all about how filter bitsets are working. The first article has been posted a few years ago, but the logic underneath is still pretty much the same in recent versions.
Also here is another article worth looking at.

I'm trying to get the Python package OSMnx running on my Windows10 machine. I'm still new to python so struggling with the basics. I've followed the instructions here https://osmnx.readthedocs.io/en/stable/ and have successfully created a new conda environment for it to run in. The installation seems to have gone ok. However, as soon as I try and import it, I get the following error
...ANSWER
Answered 2021-Apr-28 at 10:07The module fractions is part of the Python standard library. There used to be a function gcd, which, as the linked documentation says, is:
Deprecated since version 3.5: Use
math.gcd()instead.
Since the function gcd was removed from the module fractions in Python 3.9, it seems that the question uses Python 3.9, not Python 3.7.6 as the question notes, because that Python version still had fractions.gcd.
The error is raised by networkx. Upgrading to the latest version of networkx is expected to avoid this issue:

Answered 2021-Jun-09 at 19:36Since you weren't providing the information I asked for, I tried to write a small test case, seeking to get at the core of your problem.
Mixing numpy and sympy is tricky and somewhat unpredictable. But sometimes sympy symbols can be used in numpy expressions.

Install intersection
You can use intersection 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.
