Answer 1

I assume you are working with this tutorial.

I would recommend using pandas to read your format:

import pandas as pd
import numpy as np

data = pd.read_csv('mnist_train_100.csv', header=None)

# numpy array of shape (100, 784), type float32
X_train = data.ix[:, 1:].values.astype(np.float32) 

# numpy array of shape (100,), type int64
y_train = data.ix[:, 0].values
