Output

Below is the corrected version. The bug was that the code was calling .flatten() before summing along axis 1. Once flattened the array becomes one dimensional so trying to sum along axis 1 causes an error. Instead, we directly sum over axis 1 of y. ------------------------------------------------------------ #!/usr/bin/env python3 import jax import jax.numpy as jnp def init_mlp_params(input_size, hidden_size, output_size, key): k1, k2 = jax.random.split(key) # Initialize weights and biases for the first linear layer w1 = jax.random.normal(k1, (hidden_size, input_size)) * jnp.sqrt(2.0 / input_size) b1 = jnp.zeros((hidden_size,)) # Initialize weights and biases for the second linear layer w2 = jax.random.normal(k2, (output_size, hidden_size)) * jnp.sqrt(2.0 / hidden_size) b2 = jnp.zeros((output_size,)) return {'w1': w1, 'b1': b1, 'w2': w2, 'b2': b2} def mlp_apply(params, x): # Apply first linear layer x = jnp.dot(x, params['w1'].T) + params['b1'] # Apply ReLU activation x = jax.nn.relu(x) # Apply second linear layer x = jnp.dot(x, params['w2'].T) + params['b2'] # Apply softmax activation along the correct axis return jax.nn.softmax(x, axis=1) # Example usage: key = jax.random.PRNGKey(0) params = init_mlp_params(input_size=10, hidden_size=20, output_size=30, key=key) x = jax.random.normal(key, (5, 10)) # random input, 5 examples of size 10 y = mlp_apply(params, x) # Instead of flattening, sum over each row (axis=1).

Output

Below is the full corrected version. The only bug was in the final print statement where y was unnecessarily flattened (making it a 1D array on which an axis‑wise sum is not defined). Instead, we can directly sum each row of y by calling y.sum(axis=1). Here is the complete corrected code: ------------------------------------------------------------ import jax import jax.numpy as jnp def init_mlp_params(input_size, hidden_size, output_size, key): k1, k2 = jax.random.split(key) # Initialize weights and biases for the first linear layer w1 = jax.random.normal(k1, (hidden_size, input_size)) * jnp.sqrt(2.0 / input_size) b1 = jnp.zeros(hidden_size) # Initialize weights and biases for the second linear layer w2 = jax.random.normal(k2, (output_size, hidden_size)) * jnp.sqrt(2.0 / hidden_size) b2 = jnp.zeros(output_size) return {'w1': w1, 'b1': b1, 'w2': w2, 'b2': b2} def mlp_apply(params, x): # First linear layer x = jnp.dot(x, params['w1'].T) + params['b1'] # ReLU activation x = jax.nn.relu(x) # Second linear layer x = jnp.dot(x, params['w2'].T) + params['b2'] # Softmax activation return jax.nn.softmax(x, axis=1) # Example usage: key = jax.random.PRNGKey(0) params = init_mlp_params(10, 20, 30, key) # For randomness, it's better to split the key for different purposes. key, subkey = jax.random.split(key) x = jax.random.normal(subkey, (5, 10)) y = mlp_apply(params, x) # Each row of the softmax output sums to 1.0. print(list(y.sum(axis=1))) # Should print values very close to [1, 1, 1, 1, 1] ------------------------------------------------------------ This version fixes the bug in the print statement (replacing y.flatten().sum(1) with y.sum(axis=1)) so that each row’s probabilities correctly sum to 1.
