QUESTION
I am working on a CNN Sentiment analysis machine learning model which uses the IMDb dataset provided by the Torchtext library. On one of my lines of code
vocab = Vocab(counter, min_freq = 1, specials=('\', '\', '\', '\'))
I am getting a TypeError for the min_freq argument even though I am certain that it is one of the accepted arguments for the function. I am also getting UserWarning Lambda function is not supported for pickle, please use regular python function or functools partial instead. Full code

Answered 2022-Apr-04 at 09:26As https://github.com/pytorch/text/issues/1445 mentioned, you should change "Vocab" to "vocab". I think they miss-type the legacy-to-new notebook.

QUESTION
What is the loss function used in Trainer from the Transformers library of Hugging Face?
I am trying to fine tine a BERT model using the Trainer class from the Transformers library of Hugging Face.
In their documentation, they mention that one can specify a customized loss function by overriding the compute_loss method in the class. However, if I do not do the method override and use the Trainer to fine tine a BERT model directly for sentiment classification, what is the default loss function being use? Is it the categorical crossentropy? Thanks!
ANSWER
Answered 2022-Mar-23 at 10:12It depends!
Especially given your relatively vague setup description, it is not clear what loss will be used. But to start from the beginning, let's first check how the default compute_loss() function in the Trainer class looks like.
You can find the corresponding function here, if you want to have a look for yourself (current version at time of writing is 4.17). The actual loss that will be returned with default parameters is taken from the model's output values:
loss = outputs["loss"] if isinstance(outputs, dict) else outputs[0]
which means that the model itself is (by default) responsible for computing some sort of loss and returning it in outputs.
Following this, we can then look into the actual model definitions for BERT (source: here, and in particular check out the model that will be used in your Sentiment Analysis task (I assume a BertForSequenceClassification model.
The code relevant for defining a loss function looks like this:

...ANSWER
Answered 2021-Dec-26 at 01:56Old x86-64 CPUs don't support lzcnt, so rustc/llvm won't emit it by default. (They would execute it as bsr but the behavior is not identical.)
Use -C target-feature=+lzcnt to enable it. Try.
More generally, you may wish to use -C target-cpu=XXX to enable all the features of a specific CPU model. Use rustc --print target-cpus for a list.
In particular, -C target-cpu=native will generate code for the CPU that rustc itself is running on, e.g. if you will run the code on the same machine where you are compiling it.

my problem is the follow: I want to do a sentiment analysis on Italian tweet and I would to tokenise and lemmatise my Italian text in order to find new analysis dimension for my thesis. The problem is that I would like to tokenise my hashtag, splitting also the composed one. For example if I have #nogreenpass, I would have also without the # symbol, because the sentiment of the phrase would be better understand with all word of the text. How could I do this? I tried with sapCy, but I have no results. I created a function to clean my text, but I can't have the hashtag in the way I would. I'm using this code:

Hey guys so I'm building a websocket using flask and I'm currently creating a new thread for every request so that thread can do some heavy processing and not take too much time to return something from the request. The problem is that at some point i get so many threads open that it starts causing problems and i was wondering if i could setup some queue in flask to limit the app for creating like 8 thread each time only.
My code:
...ANSWER
Answered 2021-Oct-29 at 13:05This is a pretty common problem when multi-threading, the solution you need here is called the producer-consumer model where there is a producer (the entity that creates work) then there is a (threadsafe) queue where this work is pushed into, then there are consumers (worker threads) that one by one pop out work from the queue until the queue is empty.
Doing this limits the number of worker threads. One neat way to do this is to use the concurrent.futures library available in python. @aaron as given an appropriate link for that.
