QUESTION
The Question
How do I best execute memory-intensive pipelines in Apache Beam?
Background
I've written a pipeline that takes the Naemura Bird dataset and converts the images and annotations to TF Records with TF Examples of the required format for the TF object detection API.
I tested the pipeline using DirectRunner with a small subset of images (4 or 5) and it worked fine.
The Problem
When running the pipeline with a bigger data set (day 1 of 3, ~21GB) it crashes after a while with a non-descriptive SIGKILL
.
I do see a memory peak before the crash and assume that the process is killed because of a too high memory load.
I ran the pipeline through strace
. These are the last lines in the trace:
ANSWER
Answered 2021-Jun-15 at 13:51Multiple things could cause this behaviour, because the pipeline runs fine with less Data, analysing what has changed could lead us to a resolution.
Option 1 : clean your input dataThe third line of the logs you provide might indicate that you're processing unclean data in your bigger pipeline mmap(NULL,
could mean that | "Get Content" >> beam.Map(lambda x: x.read_utf8())
is trying to read a null value.
Is there an empty file somewhere ? Are your files utf8 encoded ?
Option 2 : use smaller files as inputI'm guessing using the fileio.ReadMatches()
will try to load into memory the whole file, if your file is bigger than your memory, this could lead to errors. Can you split your data into smaller files ?
If files are too big for your current machine with a DirectRunner
you could try to use an on-demand infrastructure using another runner on the Cloud such as DataflowRunner
QUESTION
Let's say I have a collection called "pets"
The collection contains three different types of pets: cat, dog, and bird
Now let's say there are 10 cats, 10 dogs, and 10 birds in the collection (30 documents in total).
Is there a way to make a single query to pets that gets me 3 cats, 2 dogs, and 1 bird?
Basically I want to specify each type of pet I want, and limit each type of pet to a specific number, all in one query. The reason for this is because I want to be efficient and not make many queries.
This is what I have currently:

QUESTION
Let's assume I had the following table:
I want to apply a filter so that I only see the rows that contain "cat" among the comma separated "tags" in Animals column. The regular filters, of course, don't separate the possible values but instead the filter is populated with the whole string: "dog", "dog, cat", "cat, fish, bird", etc.
Is there a way to get the filter to populate with the individual values "dog", "cat", "fish", etc.?
Alternatively, would you suggest a different table layout to achieve a similar solution, still using the manual filters? One that does not require one column per possible animal type, with boolean value.
Finally, if no solution is possible, of course there is always the option to do it with formulas, something like adding a separate cell whose input is searched in the Animals column and the corresponding entries are shown/hidden, but that is not what I am aiming for.

The following code allows me to print a CSV output with the first "column" for the word and the second for the frequency. However, I have a second list called B that should be output in the same file.
...ANSWER
Answered 2021-Jun-10 at 19:15Use itertools.zip_longest()
to pair up two sequences, and add filler when one is shorter than the other. You can fill with an empty tuple, so those columns will be omitted when you combine the two tuples.
Use the csv
module to convert these combined tuples to rows in the file.

QUESTION
In Go, is there a way to implement an interface using a method, where the return type of the corresponding method in the implementation is a "wider than" the expected return type?
This is difficult to explain so here is an example. I get this error when running the below example code in Go Playground:
...ANSWER
Answered 2021-Jun-08 at 17:25Go's type system uses type name match. This would fail even if the same interface is returned with a different type name.
However, you can declare the method to satisfy the interface, but return a wider implementation that can be type-asserted.

I have a table in postgres with a value
column that contains string arrays. My objective is to find all arrays that contain any of the following strings: {'cat', 'dog'}
ANSWER
Answered 2021-Jun-08 at 17:51You can use &&
operator to find out whether two array has been overlapped or not. It will return true only if at least one element from each array match.

I am trying to get some elevations for bird locations I have in NZ. I thought I might use the code provided as an answer to a similar question (Extracting elevation from website for lat/lon points in Australia, using R), unfortunately I get errors when using the extract function in the raster package, even though the code is almost identical.
...ANSWER
Answered 2021-Jun-08 at 07:11I don't know exactly why, but the subtle reason is that, compared to Australia, getData
returns a different data structure for New Zealand. It returns a list, where the RasterLayers are in the first (and second) list element:
