Did you implement the `combine_vectors`

function?

**Update**

I assume you have a problem with the torch.randn function. It takes a shape as the first argument and it should be a tuple. In your case it will be something like this:

```
x = torch.randn((n_samples, z_dim))
y = torch.randn((n_samples, n_classes))
combine_vectors(x, y)
```

Note that the shape `(n_samples, z_dim)`

is surrounded by extra parentheses, which are nothing more than a tuple.

yes. I did implemented it

check my updated answer

I guess this is because the `mnist_shape`

is a tuple that represents a size of `mnist`

images and you should pass a batch size instead. I assume the first value of `mnist_shape`

is the batch size, so you can call the function as follows:

```
x = torch.randn((mnist_shape[0], z_dim))
```

It would be helpful if you post your code snippet and also print the shape of the parameters.

Could you please point me to the assignment as well as the line of code where the error occurs?

Maybe try directly as:

```
generator_input_dim = z_dim + n_classes # None
discriminator_im_chan = mnist_shape[0] + n_classes # None
```

The `get_input_dimensions`

function should return exactly that — the input dimensions, i.e. two **integers** that represent the dimensionality of the conditional generator and the number of input channels to the discriminator.

You shouldn’t generate a random tensor with those dimensions, as that is not what the function is for.

As @pedrorohde mentioned the function is not asking you create tensors, it’s asking the dimensionality of the conditional generator and the number of input channels to the discriminator. If you read the description of function carefully you will able to figure out the right ans. You don’t need to create tensors with those dimensions.
