Hi all. I would like to use cvqnn\_layers\_all to convert parameters to torch tensor  
inits = torch.tensor(cvqnn\_layers\_all(L, M, seed=0), dtype=torch.float64)

however when I wanted to check the documentation it says that page for cvqnn\_layers\_all does not exist anymore. Can you suggest any method instead of cvqnn\_layers\_all to convert to tensor?

Thank you,  
Aigerim

Hi @Aigerim,

The following code from the [CVNeuralNetLayers docs](https://pennylane.readthedocs.io/en/latest/code/api/pennylane.CVNeuralNetLayers.html) should help you.

```
shapes = CVNeuralNetLayers.shape(n_layers=2, n_wires=2)
weights = [np.random.random(shape) for shape in shapes]

def circuit():
  CVNeuralNetLayers(*weights, wires=[0, 1])
  return qml.expval(qml.X(0))

```

Please let me know if this solves your problem!
