QUESTION
I'm trying to run through some image recognition tutorials, but I keep running into this error that's preventing me from proceeding. I'm running Ubuntu 21.10, and Python 3.9.7. My code is as such.
...ANSWER
Answered 2021-Nov-17 at 18:56I got the same issue after upgrading to Ubuntu 21.10 (from 20.10).
Installing an older version of OpenCV worked for me.
QUESTION
I am trying to code a bot to automate some tasks on a videogame with JS and Node, so far I've been using RobotJS. The problem I'm facing is that I need to find something on the screen as it moves from time to time to then click on it. Something similar to PyAutoGUI locateOnScreen()
function.
It needs to use AI to have some tolerance too, as the image will not be exactly the same from time to time, though it's almost the same so I think any basic AI for image recognition would detect it fine.
Does anyone have an idea on what to use for this specific case?

QUESTION
I have a dataset of tens of thousands of dialogues / conversations between a customer and customer support. These dialogues, which could be forum posts, or long-winded email conversations, have been hand-annotated to highlight the sentence containing the customers problem. For example:
Dear agent, I am writing to you because I have a very annoying problem with my washing machine. I bought it three weeks ago and was very happy with it. However, this morning the door does not lock properly. Please help
Dear customer.... etc
The highlighted sentence would be:
However, this morning the door does not lock properly.
- What approaches can I take to model this, so that in future I can automatically extract the customers problem? The domain of the datasets are broad, but within the hardware space, so it could be appliances, gadgets, machinery etc.
- What is this type of problem called? I thought this might be called "intent recognition", but most guides seem to refer to multiclass classification. The sentence either is or isn't the customers problem. I considered analysing each sentence and performing binary classification, but I'd like to explore options that take into account the context of the rest of the conversation if possible.
- What resources are available to research how to implement this in Python (using tensorflow or pytorch)
I found a model on HuggingFace which has been pre-trained with customer dialogues, and have read the research paper, so I was considering fine-tuning this as a starting point, but I only have experience with text (multiclass/multilabel) classification when it comes to transformers.
...ANSWER
Answered 2022-Feb-07 at 10:21This type of problem where you want to extract the customer problem from the original text is called Extractive Summarization and this type of task is solved by Sequence2Sequence
models.
The main reason for this type of model being called Sequence2Sequence
is because the input and the output of this model would both be text.
I recommend you to use a transformers model called Pegasus which has been pre-trained to predict a masked text, but its main application is to be fine-tuned for text summarization (extractive or abstractive).
This Pegasus model is listed on Transformers library, which provides you with a simple but powerful way of fine-tuning transformers with custom datasets. I think this notebook will be extremely useful as guidance and for understanding how to fine-tune this Pegasus model.

I have created a spacy transformer model for named entity recognition. Last time I trained till it reached 90% accuracy and I also have a model-best
directory from where I can load my trained model for predictions. But now I have some more data samples and I wish to resume training this spacy transformer. I saw that we can do it by changing the config.cfg

Answered 2022-Jan-20 at 07:21The vectors setting is not related to the transformer
or what you're trying to do.
In the new config, you want to use the source

blocks to contain only the source

QUESTION
I am using Microsoft Computer Vision API for OCR processing and I noticed that they are getting charged as S3 transactions instead of S2 in my bill.
I'm using the .NET SDK and the API I am using is this one. https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.cognitiveservices.vision.computervision.computervisionclientextensions.readasync?view=azure-dotnet
I have also confirmed that the actual REST API the SDK calls is the following POST /vision/v3.2/read/analyze https://centraluseuap.dev.cognitive.microsoft.com/docs/services/computer-vision-v3-2/operations/5d986960601faab4bf452005
According to documentation, that should be the OCR Read API, am I correct? https://docs.microsoft.com/en-us/azure/cognitive-services/computer-vision/vision-api-how-to-topics/call-read-api
I am puzzled as to why my calls are getting charged as S3 instead of S2. This is important for me because S3 is 50% more expensive than S2. Using the Pricing Calculator, 1000 S2 transactions is $1, whereas 1000 S3 transactions is $1.5. https://azure.microsoft.com/en-us/pricing/calculator/?service=cognitive-services
What's the difference between OCR and "Describe and Recognize Text" anyways? OCR (Optical Character Recognition) by definition must recognize text. I am calling the Read API without any of the optional parameters so I did not ask for "Describe" hence the call should be S2 feature rather than S3 feature I think.
I already posted this question at Microsoft Q&A but I thought SO might get more traffic hence help me get an answer faster. https://docs.microsoft.com/en-us/answers/questions/689767/computer-vision-api-charged-as-s3-transaction-inst.html
...ANSWER
Answered 2022-Jan-12 at 14:19To help you understand, you need a bit of history of those services. Computer Vision API (and all "calling" SDKs, whether C#/.Net, Java, Python etc using these APIs) have moved frequently and it is sometimes hard to understand which SDK calls which version of the APIs.
API operations historyRegarding optical character reading operations, there have been several operations:
Computer Vision 1.0See definition here was containing:
OCR
operation, a synchronous operation to recognize printed textRecognize Handwritten Text
operation, an asynchronous operation for handwritten text (with "Get Handwritten Text Operation Result" operation to collect the result once completed)
See definition here. OCR was still there, but "Recognize Handwritten Text" was changed. So there were:
OCR
operation, a synchronous operation to recognize printed textRecognize Text
operation, asynchronous (+ Get Recognize Text Operation Result to collect the result), accepting both printed or handwritten text (seemode
input parameter)Batch Read File
operation, asynchronous (+ "Get Read Operation Result" to collect the result), which was also processing PDF files whereas the other one were only accepting images. It was intended "for text-heavy documents"
Computer Vision 2.1 was similar in terms of operations.
Computer Vision 3.0See definition here.
Main changes: Recognize Text
and Batch Read File
were "unified" into a Read
operation, with models improvements. No more need to specify handwritten / printed for example (see link).

QUESTION
I'm new to AWS and it's services. What I want to achieve is a multi-tenancy SaaS application. What my concept looks like: I use Cognito for user authentication. There all users no matter what tenant they belong to should use one frontend to login. For the tenant-recognition I use a custom attribute "custom:tenant" which I get from the JWT when the login is successful. For the applicantion itself I want to use VPCs and to ensure encapsulation each tenant should have their own VPC.
Example:
- User A of Tenant 1 login and gets back JWT with claim "custom:tenant":"1" should be routed to VPC 1
- User B of Tenant 2 login and gets back JWT with claim "custom:tenant":"2" should be routed to VPC 2
Now my question is: how do I achieve this routing from the success of the login to the appropriate VPC? Do I need further Services for that or where do I find these settings?
...ANSWER
Answered 2021-Dec-10 at 21:18There is a standard content based routing technique for routing based on the contents of JWTs. This type of thing is usually managed by a reverse proxy or API gateway placed in front of APIs, which runs some custom logic to read the JWT and route accordingly. This also keeps the plumbing outside of application components.
EXAMPLE
Here is an NGINX example coded in LUA, a high level scripting language, to read the JWT and extract a claim. In this example it is a zone whereas in your case it is a tenant ID:
PREREQUISITES
Not all middleware supports this type of routing though. Eg you won't be able to do it in a simple load balancer. One option might be to use NGINX as a cloud managed service though it will cost money. A good gateway in front of APIs is an important architectural component though, so see if your company feels it is worth investing in.
