Hello l have a list of tensors Y obtained by concatenating 10 tensors each of dimension (16,32,3) . Hence Y is of dimension [10,16,32,3].

Now l would like to concatenate Y using torch.cat() as follow :

```
Y = []
for O in np.arange(len(x)):
x_p = self.conv_layer(x[O])
Y.append(x_p)
```

Then l apply torch.cat() to Y as follow :

```
x = torch.cat(Y)
```

However :

```
x.size()
torch.Size([160, 32, 3])
```

Rather than :

`torch.Size([10,16, 32, 3])`

What is wrong with my code ?

Thank you
