I. Bringing in the Data

I used Google Colab as my editor. Using Python, type this in the notebook:

!pip install kaggle

Next, upload the kaggle.json file that you downloaded from Kaggle:

from google.colab import filesfiles.upload()

Once uploaded, run this:

!mkdir ~/.kaggle!cp kaggle.json ~/.kaggle/!chmod 600 ~/.kaggle/kaggle.json!kaggle datasets download -d jakeshbohaju/brain-tumor

Unzip the files:


Use Pandas to bring in the dataset:

# prompt: read Brain Tumor.csv into pandas dfimport pandas as pddf = pd.read_csv("/content/Brain Tumor.csv")

II. Train-Test

First, drop the Image column from the dataset because that is just a image number.

import pandas as pdfrom sklearn.model_selection import train_test_split# Assuming your DataFrame is called df# Drop the 'Image' columndf_without_image = df.drop(columns=['Image'])

Next, we know from our data that the class is in a column called class. In order to set it, we can set the class to Y and the rest of the features to X:

# Split the data into df_val (33%) and df (rest of the data)df,df_val = train_test_split(df_without_image, test_size=0.33, random_state=42)# Now you have df_val with 33% of the data and df with the rest of the data# Split the DataFrame df into features (X) and target (y)X = df.drop(columns=['Class']) # Featuresy = df['Class'] # Target# Split the data into… Read the full blog for free on Medium.
