[Day 183] Failing to install Kubeflow, and setting up mlflow on GCP

 Hello :)
Today is Day 183!


Today is actually past the half-way point in this blog journey. 182 days to go!


A quick summary of today:
  • setting up mlflow for experiment tracking in GCP


Today I started looking at tools I can use for my MLOps zoomcamp project. I used Mage for the data engineering project so now for an orchestrator I want to try another tool.

My first idea (which I had on my mind for a while) is Kubeflow. Tldr - it is so hard to set up locally and I could not find a guide that clearly explains how :( 

I had this 1hr video in my 'to watch' for a bit and it goes over building an ML pipeline in kubeflow however it does not go over how to install from kubeflow from 0 to what is needed in the video. Then I started looking in kubeflow's documentation - I tried to set it up on GCP but I could not and actually was a bit adamant to use it because it explicitly said that the free credits on GCP do not cover kubeflow hosting costs. So ~ I started looking into local deployment. There were 3 different posts (1 of which from IBM) that were from 2023 and all set it up differently from nothing to kubeflow, but ... none of them work :( I was losing hope as I was investing so much time and I could not, not even use it, just install and set up kubeflow...
At some points I got to the part where I have a kubeflow cluster running and can go to localhost:8080 but I could not run a pipeline due to some error. 

I decided to step back a bit, and set up something more basic - mlflow. 
I did it locally, but for this project I wanted to use GCP. 

I created a Compute Engine 
Created a storage bucket for mlflow artifacts
Using SSH I went into the VM and installed mlflow and set up a sqlite db. I decided to use sqlite because:
  1. I will not have that many experiments to keep
  2. creating an SQL db on GCP seems expensive to keep active
Then I tried running a simple experiment locally, but I was getting a weird error from mlflow: Anonymous credentials cannot be refreshed

it seemed related to my GCP credentials so I thought that I needed to add my creds.json file to the VM so that it can access them - did that but it was not the issue.

Turns out, in the jupyter notebook I needed to explicitly point to the creds.json file 
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = 'my-creds.json'
and with that my issue was fixed and now mlflow hosted on GCP worked. 

Though I failed to do anything with kubeflow today, I will not give up. I used Mage for orchestration in the data eng project, so now I will try to use another tool like Prefect (if not Kuberflow). But still, nothing is certain, so I will not be surprised if I write in tomorrow's post that I am using Mage for this project too. Mage is pretty nice ^^

I uploaded the parts of my project to this GitHub repo.


That is all for today!

See you tomorrow :)

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

 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
