[Day 187] Setting up postgres, pgAdmin, Grafana and FastAPI to run in Docker

 Hello :)
Today is Day 187!


A quick summary of today:
  • creating a docker container with postgres db, pgadmin, grafana and fastapi
  • a small Glaswegian project update


Docker and I are becoming closer and closer friends ^^

Before going into that, I will go in order of things I did today.


All files and code from today, and up until this point are on my repo.


Firstly, monitoring with Evidently

I learned about Evidently from the mlops zoomcamp, and it looked very easy to use, so I gave it a try. 

In order to generate the reports, I decided to use my data before creating dummies. Because the balanced random forest classifier model uses a dataset with all dummies (all categorical data). So in order for the monitoring to be a bit more understandable, I decided to use the 'pre-dummy' dataset, and below are some parts of the generated reports by Evidently. 

There is variable info:

Missing values:

Drift:

Model performance:

The reports (as html) are on my repo in the monitoring/evidently_reports folder.


Next ~ Grafana

In the zoomcamp we were thought of both Evidently and Grafana. And I see that Grafana is a more flexible tool for monitoring that allows easier data integration from multiple resources.

I *did* start a grafana server, however I started thinking about PostgreSQL. 

I started to think that I do not want to use GCS for all my files - it might be better practice and a good exercise to think of GCS as a storage for keeping just some raw files, while I can use a postgres server for intermediate data.

So I started to set up Grafana and a postgres server, and then I added pgAdmin using Docker. Then I decided to combine these services with the FastAPI docker service I established yesterday - so all runs together. And this is where I spent most of my time today. 

I had little folder mapping probles, however the biggest one - I kept getting 'anonymous credentials cannot be refreshed' from google. I use GCS to download a model for FastAPI. It worked completely fine locally, but when I run the FastAPI server from docker the error kept coming up. I kept just chaning paths to try to point the env to the credentials file, but nothing worked. In the end... I went to what I had originally (this is after ~2 hours of trying to fix this) and it ran... haha 

So now, with make the command `make start-all` I run postgres, pgAdmin, grafana, and fastAPI. 

Since I have postgres now, I left some TODOs for tomorrow - removing all reads of local file data, now I should read from postgres (rather than GCS only) - I think I have 4 such TODOs. 


On another note, a small Glaswegian dataset update

We are up to 86 minutes of audio. And our fine-tuned whisper is performing very well (according to my Scottish project partner), so I will try to help a bit with the transcription and send just some notes on what he might need to double-check to make sure whisper and I transcripbed a clip correctly. 


That is all for today!

See you tomorrow :)

[Day 198] Transactions Data Streaming Pipeline Porject [v1 completed]

Image
 Hello :) Today is Day 198! A quick summary of today: data streaming pipeline project [v1 done] Here is a link to the project's repo. Well ... I did not know I can do it in a day (~14 hours) after yesterday's issues but here we are. Turns out in order to insert the full (~70 variables with nested/list structure), I need the proper pyspark schema. And yesterday I did not have that and that is why when I was reading data in the kafka producer I was getting NULL in the columns - my schema was wrong. Well today I not only fixed the schema for the 4 variables I had yesterday, but included *all* the variables that come from the Stripe API ~ 70 (for completeness).  When I run docker-compose, the data streams and is input into the postgres db (and is still running). Unfortunately, the free Stripe API for creating realistic transactions has a limit of 25, so every 3 seconds, 25 new transactions are sent to the db. It has been running half the day (since I got that set up) and as I am wr

[미리 공부] 기초 통계 복습 (Day 1는 1월2일)

Image
모험을 시작하기 전에 기초 지식을 복습하고자 했다. 오늘 SPSS 대안 프로그램을 찾아보려고 해서 JASP에 대해 알게 되었다. 유용한 프로그램인 것 같아서 선회귀와 기술통계를 내려고 했는데 재미있었다. 그런데 JASP에 대해 더 알기 전에 '기초 통계 지식을 좀 복습을 하고자 하면 좋을 것 같아'란 생각을 들었다. 다행히, Coursera에서 Stanford University의 Guenther Walther 교수님께서 진행된  Introduction to Statistics  무료 강좌가 있다.  좀 부족한 부분은 다양한 검정통계 하는 거고 (F test, t-test, chi-square 등) 이제 JASP 아니면 다른 통계 프로그램 사용하게 되어도 이런 부분을 좀 더 자세히 집중하여 공부하면 된다.  특히 homoscedasticity 및 heteroscedasticity 개념을 기억에 남았다. Homoscedasticity (선): Definition: In a homoscedastic dataset, the variance of the errors (residuals) is constant across all levels of the independent variable(s). In simpler terms, the spread of the residuals is the same throughout the range of predictor values. Heteroscedasticity (악): Definition: Heteroscedasticity occurs when the variance of the errors is not constant across all levels of the independent variable(s). In other words, the spread of residuals changes as the values of the independent variable(s) change. (Udemy 사진) 강의

[Day 61] Stanford CS224N (NLP with DL): Machine translation, seq2seq + a side CDCGAN mini project

Image
 Hello :) Today is Day 61! A quick summary of today: Covered Lecture 7 : machine translation, seq2seq, attention from Stanford CS224N Tried to make a conditional DCGAN to generate MNIST numbers ( colab ) ( kaggle ) I will first cover the GAN story (then will share my notes from the lecture) So... while watching and taking notes today, I started thinking, what if I can use my notes as data to a model and afterwards, when I want, I can give it raw string text and it will output text in the format of my notes (with my handwriting). Well I started looking around and actually the first model architecture that came to my mind was the GAN (specifically conditional GAN) - I remembered there was a GAN architecture that alongside the pictures, we can give it the labels, and then on-demand generate. In retrospect, there are of course others, but I decided to go with GAN.  For maybe 2 hours I busted my head trying to make a simple model with the EMNIST dataset (english characters), and I kept gett
