Creating a detailed README file that outlines the entire process from storing data on GCP to building a machine learning model involves several steps. Below is a structured guide you can include in your README file:
This guide outlines the process of using Google Cloud Platform (GCP) services to store and process data, querying data with BigQuery, manipulating data using Pandas, and building a machine learning model to predict house prices.

In this project, we utilize GCP for data storage and processing, specifically using Google Cloud Storage for storing datasets and BigQuery for querying large datasets. We then use Pandas for data manipulation and finally build a machine learning model to predict house prices based on the processed data.
Before proceeding, ensure you have the following prerequisites:
- Google Cloud Platform (GCP) account with necessary permissions.
- Python environment with necessary libraries (
google-cloud-bigquery
,pandas
,scikit-learn
, etc.). - Authentication credentials set up to access GCP services programmatically.
-
Upload Data to Google Cloud Storage (GCS):
- Upload your dataset (e.g., CSV file) to a bucket in GCS using the GCP Console or
gsutil
command-line tool.
gsutil cp <local-file-path> gs://<your-bucket-name>/<destination-path>
- Upload your dataset (e.g., CSV file) to a bucket in GCS using the GCP Console or
-
Verify Upload:
- Ensure the data file is successfully uploaded to GCS by checking the bucket through the GCP Console or using
gsutil
.
- Ensure the data file is successfully uploaded to GCS by checking the bucket through the GCP Console or using
-
Create Dataset and Table in BigQuery:
- Use the BigQuery Console or
bq
command-line tool to create a dataset and table schema based on your uploaded data.
bq mk --dataset <dataset-id> bq load --source_format=CSV <dataset-id>.<table-id> gs://<your-bucket-name>/<file-name>.csv
- Use the BigQuery Console or
-
Query Data:
- Write SQL queries in the BigQuery Console or programmatically using the
google-cloud-bigquery
Python library to extract relevant data for analysis.
from google.cloud import bigquery # Initialize BigQuery client client = bigquery.Client() # Write and execute SQL query query = """ SELECT * FROM `project_id.dataset_id.table_id` """ df = client.query(query).to_dataframe()
- Write SQL queries in the BigQuery Console or programmatically using the
-
Load Data into Pandas DataFrame:
- Use the
to_dataframe()
method from thegoogle-cloud-bigquery
library to load queried data into a Pandas DataFrame for manipulation.
import pandas as pd # Manipulate data using Pandas df_processed = df.copy() # Example: Perform data cleaning, feature engineering, etc.
- Use the
-
Data Preprocessing:
- Perform preprocessing steps such as handling missing data, encoding categorical variables, and scaling numerical features.
from sklearn.preprocessing import StandardScaler scaler = StandardScaler() X = scaler.fit_transform(df_processed[['feature1', 'feature2', ...]]) y = df_processed['target']
-
Choose and Train Model:
- Select an appropriate machine learning algorithm (e.g., Linear Regression, Random Forest) and train the model using the preprocessed data.
from sklearn.linear_model import LinearRegression model = LinearRegression() model.fit(X_train, y_train)
-
Evaluate Model Performance:
- Evaluate the model using appropriate metrics (e.g., Mean Squared Error, R-squared) on a test set.
from sklearn.metrics import mean_squared_error y_pred = model.predict(X_test) mse = mean_squared_error(y_test, y_pred)
