I HAVE the model code as:
class RNN(nn.Module):
“”“RNN module(cell type lstm or gru)”“”
def init(
self,
input_size,
hid_size,
num_rnn_layers=1,
dropout_p = 0.2,
bidirectional = False,
rnn_type = ‘lstm’,
):
super().init()
if rnn_type == 'lstm':
self.rnn_layer = nn.LSTM(
input_size=input_size,
hidden_size=hid_size,
num_layers=num_rnn_layers,
dropout=dropout_p if num_rnn_layers>1 else 0,
bidirectional=bidirectional,
batch_first=True,
)
else:
self.rnn_layer = nn.GRU(
input_size=input_size,
hidden_size=hid_size,
num_layers=num_rnn_layers,
dropout=dropout_p if num_rnn_layers>1 else 0,
bidirectional=bidirectional,
batch_first=True,
)
def forward(self, input):
outputs, hidden_states = self.rnn_layer(input)
return outputs, hidden_states
class RNNModel(nn.Module):
def init(
self,
input_size,
hid_size,

self.rnn_layer = RNN(
input_size=46,#hid_size * 2 if bidirectional else hid_size,
hid_size=hid_size,
rnn_type=rnn_type,
bidirectional=bidirectional
)
self.conv1 = ConvNormPool(
input_size=input_size,
hidden_size=hid_size,
kernel_size=kernel_size,
)
self.conv2 = ConvNormPool(
input_size=hid_size,
hidden_size=hid_size,
kernel_size=kernel_size,
)
self.avgpool = nn.AdaptiveAvgPool1d((1))
self.fc = nn.Linear(in_features=hid_size, out_features=n_classes)
def forward(self, input):
print("shape")
print(input.shape) # **shape isshape torch.Size([32, 1, 187])**
x = self.conv1(input)
x = self.conv2(x)
x, _ = self.rnn_layer(x)
x = self.avgpool(x)
x = x.view(-1, x.size(1) * x.size(2))
x = F.softmax(self.fc(x), dim=1)#.squeeze(1)
return x
when I create 
m1=RNNModel(1, 64, ‘lstm’, True).to(device)
and run

Why is this so??Pls help
