Note that in JAX, the `Dense` layer is equivalent to `torch.nn.Linear`, and the activation function `relu` and `softmax` are defined in `jax.nn`. Also, instead of using `torch.randn` to generate random inputs, we use `jnp.random.normal` in JAX. In addition, the `init_params` function is not necessary in JAX since the parameters are initialized when the `MLP` class is created. Also, note that JAX does not have a built-in equivalent to `torch.nn.Module`, so we simply define the `MLP` class without inheriting from any other class. Finally, in JAX, the `__call__` method is used to define the forward pass of the model, and the `y = model(x)` call is equivalent to `y = model.__call__(x)` in PyTorch.

Replace random initialization with appropriate initialization as needed. This example uses the same random seed for simplicity. The JAX code defines an `MLP` class with a similar structure to the original PyTorch code, but using JAX functions and JAX numpy arrays instead of PyTorch tensors. The forward pass is defined inside the `__call__` method, and the initialization of the model parameters is done in the `initialize_params` method. Note that JAX does not use the concept of layers as in PyTorch, so the linear layers and activation functions are implemented directly in the neural network function. Also, JAX does not have a direct equivalent to PyTorch's functional module, so the softmax function is imported from `jax.nn`. Note: The JAX code provided here assumes that you have installed the JAX library and its dependencies. You can install JAX using `pip install --upgrade jax jaxlib`. For more information about JAX, you can check the official documentation at https://jax.readthedocs.io/en/latest/.

Note: 1. In JAX, you can use the `flax` library to define neural network modules similar to PyTorch's `nn.Module`. 2. Instead of using `torch.nn.Linear`, you can use `nn.Dense` in `flax`. 3. In JAX, the activation functions like ReLU and softmax are available in `jax.nn`. 4. To initialize the parameters of the model, you can use `model.init` instead of calling the model on some dummy input. 5. To apply the model to some input, you can use `model.apply` function. 6. To generate random numbers, you can use `random.normal` function in JAX. 7. Instead of using `numpy()` to convert the output to a NumPy array, you can use `jnp.array()` to convert it to a JAX array. 8. To flatten the output, you can use `jnp.ravel()` function in JAX. 9. To compute the sum of the elements along an axis, you can use `jnp.sum()` function in JAX.

Note that JAX does not have a direct equivalent to PyTorch's `nn.Module`, so we are defining our own `MLP` class with the necessary components. Also, JAX does not have an exact equivalent to PyTorch's `nn.functional.softmax`, so we are using `jax.nn.softmax` instead. Finally, in PyTorch the `nn.Linear` layer initializes its weights using various strategies, while in this JAX code we are simply initializing the weights using random normal distributions. Also, note that in JAX, the `grad` function is used to compute gradients instead of PyTorch's `backward` function. If you need to compute gradients in your JAX code, you can use the `grad` function to define a gradient computation function, like this: 
1
2
model_grad = jit(grad(model))
gradient = model_grad(x)
Here, `model_grad` is a function that takes an input `x` and returns the gradient of the model's output with respect to its parameters. The `gradient` variable then stores the computed gradient for the input `x`.

Note that this example uses JAX's `random.normal` function to initialize the weights of the MLP instead of the PyTorch equivalent `torch.nn.init.xavier_uniform_`. You can replace it with any other weight initialization if needed. Also, this example uses JAX's `random.PRNGKey` to generate random numbers for weight initialization. You can replace this with another source of randomness if needed.
