kandi X-RAY | nmt Summary
Sequence-to-sequence (seq2seq) models (Sutskever et al., 2014, Cho et al., 2014) have enjoyed great success in a variety of tasks such as machine translation, speech recognition, and text summarization. This tutorial gives readers a full understanding of seq2seq models and shows how to build a competitive seq2seq model from scratch. We focus on the task of Neural Machine Translation (NMT) which was the very first testbed for seq2seq models with wild success. The included code is lightweight, high-quality, production-ready, and incorporated with the latest research ideas. We achieve this goal by:.

QUESTION
I have an java app (JDK13) running in a docker container. Recently I moved the app to JDK17 (OpenJDK17) and found a gradual increase of memory usage by docker container.
During investigation I found that the 'serviceability memory category' NMT grows constantly (15mb per an hour). I checked the page https://docs.oracle.com/en/java/javase/17/troubleshoot/diagnostic-tools.html#GUID-5EF7BB07-C903-4EBD-A9C2-EC0E44048D37 but this category is not mentioned there.
Could anyone explain what this serviceability category means and what can cause such gradual increase? Also there are some additional new memory categories comparing to JDK13. Maybe someone knows where I can read details about them.
Here is the result of command jcmd 1 VM.native_memory summary
ANSWER
Answered 2022-Jan-17 at 13:38Unfortunately (?), the easiest way to know for sure what those categories map to is to look at OpenJDK source code. The NMT tag you are looking for is mtServiceability. This would show that "serviceability" are basically diagnostic interfaces in JDK/JVM: JVMTI, heap dumps, etc.
But the same kind of thing is clear from observing that stack trace sample you are showing mentions ThreadStackTrace::dump_stack_at_safepoint
-- that is something that dumps the thread information, for example for jstack
, heap dump, etc. If you have a suspicion for the memory leak in that code, you might try to build a MCVE demonstrating it, and submitting the bug against OpenJDK, or showing it to a fellow OpenJDK developer. You probably know better what your application is doing to cause thread dumps, focus there.
That being said, I don't see any obvious memory leaks in StackFrameInfo
, neither can I reproduce any leak with stress tests, so maybe what you are seeing is "just" thread dumping over the larger and larger thread stacks. Or you capture it when thread dump is happening. Or... It is hard to say without the MCVE.
Update: After playing with MCVE, I realized that it reproduces with 17.0.1, but not with either mainline development JDK, or JDK 18 EA, or JDK 17.0.2 EA. I tested with 17.0.2 EA before, so was not seeing it, dang. Bisection between 17.0.1 and 17.0.2 EA shows it was fixed with JDK-8273902 backport. 17.0.2 releases this week, so the bug should disappear after you upgrade.
QUESTION
I'm getting the error message:
Subquery returned more than 1 value. This is not permitted when the subquery follows =,!=,<,<=,>,=> or when the subquery is used as an expression.
Below is a small subset of a larger query, but the part of the query to determine the Test_Col
value is essentially where I'm running into this issue. The query by itself works, but when I use it as a subquery within the larger query, I get this error message in SQL Server. Any ideas on where I'm going wrong?
ANSWER
Answered 2022-Jan-09 at 05:25In SQL Server DB if your subquery is written after the select
command where we wrote field name list, then your subquery must be return only one record and only one field, else you will get an error. In your script, you wrote subquery before the from
command, after this Loan_Num,
. I did a little research on your subquery. Your subquery will return more than 1 record in most cases. The reason is that you wrote group by nml.hprop
and after the where
command you wrote this condition nml.hprop in (2380, 3348)
. I would have written this query for you myself, but I don't know your business logic and what need you. If your subquery must return more than 1 record, so you must join this subquery to the main query, using inner join
or left join
, you can not write this subquery on the field list.

Answered 2021-Dec-28 at 17:32The idea of using split
is correct but assigning directly in this way in a for loop will not change the list elements.
You should also avoid using split
as a variable name when it is already the name of an inbuilt method.
A list comprehension will do the job:
QUESTION
I'm currently comparing various pre-trained NMT models and can't help but wonder what the difference between MarianMT and OpusMT is. According to OpusMT's Github it is based on MarianMT. However in the Huggingface transformers implementation all pretrained MarianMT models start with "Helsinki-NLP/opus-mt". So I thought it was the same, but even though they're roughly the same size, they yield different translation results.
If someone could please shed some light on what the differences are I would be very thankful.
...ANSWER
Answered 2021-Dec-18 at 14:43Marian is an open-source tool for training and serving neural machine translation, mostly developed at the University of Edinburgh, Adam Mickiewicz University in Poznań and at Microsoft. It is implemented in C++ and is heavily optimized for MT, unlike PyTorch-based Huggingface Transformers that aim for generality rather than efficiency in a specific use case.
The NLP group at the University of Helsinki trained many translation models using Marian on parallel data collected at Opus, and open-sourced those models. Later, they also did a conversion of the trained model into Huggingface Transformers and made them available via the Huggingface Hub.
MarianMT is a class in Huggingface Transformers for imported Marian models. You can train a model in Marian and convert it yourself. OpusMT models are Marian models trained on the Opus data in Helsinki converted to the PyTorch models. If you search the Huggingface Hub for Marian, you will find other MarianMT models than those from Helsinki.
QUESTION
I have a data structure that collates potential case insensitive naming clashes.
caseInsensitiveDuplicates
Think of the nested maps as a way of doing a compound key.
The integer represents a type of data that may have duplicates,
the first String is the uppercase version of the string
the set that follows could contain any number of versions.. .. so JEREMY: ['Jeremy', 'jeremy','JEREMY'] etc is plausible data.
The goal is to identify when the Set contains more than one entry. Upper and lowercase versions of data can co-exist, and I have to identify those cases. Hence this data structure.
- so the data N1 and n1 will be two entries keyed on the uppercase N1, and I am looking to get that back in the results.
There is a call to filter this via Streams:
- I have to work on EntrySet to keep keys/values together. I know that much.
- I want to return the same data structure I started out with (the type of caseInsensitiveDuplicates)
- I know I need to filter on the size exceeding 1.
(My actual code has an enum where Integer is, and a custom class where String is within the Set on the line where it's declared. See code below).
From initial data like so:
...ANSWER
Answered 2021-Nov-10 at 15:36I could not figure out how to do this without resorting to building it manually. If someone else comes up with the correct way to do this with Streams, I will accept that as the answer.
Have revised this solution, thanks to @Holger for the following tips:
entrySet().forEach(…)
-> functional style:forEach((k,v) -> ...)
- computeIfAbsent
map.keySet().size() == 0
-> abridgedmap.isEmpty()
