Hello,

I am trying to run a CNN that looks like this:

```
> class MyModel(nn.Module):
> def __init__(self):
> super(MyModel, self).__init__()
> self.conv1 = nn.Conv1d(1, 3, kernel_size=3)
> self.conv2 = nn.Conv1d(3, 6, kernel_size=6)
> self.conv3 = nn.Conv1d(6, 12, kernel_size=12)
> self.conv4 = nn.Conv1d(12,24, kernel_size=24)
> self.conv5 = nn.Conv1d(24,48, kernel_size = 48)
> self.conv_drop = nn.Dropout2d()
> self.conv6_transpose = nn.ConvTranspose1d(48,24, kernel_size = 48)
> self.conv7_transpose = nn.ConvTranspose1d(24,12, kernel_size = 24)
> self.conv8_transpose = nn.ConvTranspose1d(12,6, kernel_size = 12)
> self.conv9_transpose=nn.ConvTranspose1d(6,3, kernel_size = 6)
> self.conv10_transpose = nn.ConvTranspose1d(3,1, kernel_size = 3)

```

However now I ge the error: **Expected 3-dimensional input for 3-dimensional weight [3, 1, 3], but got 2-dimensional input of size [64, 200] instead.** Does anybody know what can be done now? I am relatively new to pytorch so help would be welcome

The input data is a tensor that needs to undergo several conv1d’s and transpose conv1d’s to downsample and upsample.
