                      QUESTION

                      Using RNN Trained Model without pytorch installed

                      Asked 2022-Feb-28 at 20:17

                      I have trained an RNN model with pytorch. I need to use the model for prediction in an environment where I'm unable to install pytorch because of some strange dependency issue with glibc. However, I can install numpy and scipy and other libraries. So, I want to use the trained model, with the network definition, without pytorch.

                      I have the weights of the model as I save the model with its state dict and weights in the standard way, but I can also save it using just json/pickle files or similar.

                      I also have the network definition, which depends on pytorch in a number of ways. This is my RNN network definition.

                      import torch
                      import torch.nn as nn
                      import torch.nn.functional as F
                      import torch.optim as optim
                      import random
                      
                      torch.manual_seed(1)
                      random.seed(1)
                      device = torch.device('cpu')
                      
                      class RNN(nn.Module):
                        def __init__(self, input_size, hidden_size, output_size,num_layers, matching_in_out=False, batch_size=1):
                          super(RNN, self).__init__()
                          self.input_size = input_size
                          self.hidden_size = hidden_size
                          self.output_size = output_size
                          self.num_layers = num_layers
                          self.batch_size = batch_size
                          self.matching_in_out = matching_in_out #length of input vector matches the length of output vector 
                          self.lstm = nn.LSTM(input_size, hidden_size,num_layers)
                          self.hidden2out = nn.Linear(hidden_size, output_size)
                          self.hidden = self.init_hidden()
                        def forward(self, feature_list):
                          feature_list=torch.tensor(feature_list)
                          
                          if self.matching_in_out:
                            lstm_out, _ = self.lstm( feature_list.view(len( feature_list), 1, -1))
                            output_space = self.hidden2out(lstm_out.view(len( feature_list), -1))
                            output_scores = torch.sigmoid(output_space) #we'll need to check if we need this sigmoid
                            return output_scores #output_scores
                          else:
                            for i in range(len(feature_list)):
                              cur_ft_tensor=feature_list[i]#.view([1,1,self.input_size])
                              cur_ft_tensor=cur_ft_tensor.view([1,1,self.input_size])
                              lstm_out, self.hidden = self.lstm(cur_ft_tensor, self.hidden)
                              outs=self.hidden2out(lstm_out)
                            return outs
                        def init_hidden(self):
                          #return torch.rand(self.num_layers, self.batch_size, self.hidden_size)
                          return (torch.rand(self.num_layers, self.batch_size, self.hidden_size).to(device),
                                  torch.rand(self.num_layers, self.batch_size, self.hidden_size).to(device))
                      

                      I am aware of this question, but I'm willing to go as low level as possible. I can work with numpy array instead of tensors, and reshape instead of view, and I don't need a device setting.

                      Based on the class definition above, what I can see here is that I only need the following components from torch to get an output from the forward function:

                      • nn.LSTM
                      • nn.Linear
                      • torch.sigmoid

                      I think I can easily implement the sigmoid function using numpy. However, can I have some implementation for the nn.LSTM and nn.Linear using something not involving pytorch? Also, how will I use the weights from the state dict into the new class?

                      So, the question is, how can I "translate" this RNN definition into a class that doesn't need pytorch, and how to use the state dict weights for it? Alternatively, is there a "light" version of pytorch, that I can use just to run the model and yield a result?

                      EDIT

                      I think it might be useful to include the numpy/scipy equivalent for both nn.LSTM and nn.linear. It would help us compare the numpy output to torch output for the same code, and give us some modular code/functions to use. Specifically, a numpy equivalent for the following would be great:

                      rnn = nn.LSTM(10, 20, 2)
                      input = torch.randn(5, 3, 10)
                      h0 = torch.randn(2, 3, 20)
                      c0 = torch.randn(2, 3, 20)
                      output, (hn, cn) = rnn(input, (h0, c0))
                      

                      and also for linear:

                      m = nn.Linear(20, 30)
                      input = torch.randn(128, 20)
                      output = m(input)

                      You should try to export the model using torch.onnx. The page gives you an example that you can start with.

                      An alternative is to use TorchScript, but that requires torch libraries.

                      Both of these can be run without python. You can load torchscript in a C++ application https://pytorch.org/tutorials/advanced/cpp_export.html

                      ONNX is much more portable and you can use in languages such as C#, Java, or Javascript https://onnxruntime.ai/ (even on the browser)

                              return self.model(**kwargs)
                      

                      Run an example

                      rnn = RNN(10, 10, 10, 3)
                      X = torch.randn(3,1,10)
                      h0,c0  = rnn.init_hidden()
                      print(rnn(X, h0, c0)[0])
                      

                      Use the same input to trace the model and export an onnx file

                      
                      torch.onnx.export(MWrapper(rnn), {'x':X,'h0':h0,'c0':c0}, 'rnn.onnx', 
                                        dynamic_axes={'x':{1:'N'},
                                                     'c0':{1: 'N'},
                                                     'h0':{1: 'N'}
                                                     },
                                        input_names=['x', 'h0', 'c0'],
                                        output_names=['y', 'hn', 'cn']
                                       )
                      

                      Notice that you can use symbolic values for the dimensions of some axes of some inputs. Unspecified dimensions will be fixed with the values from the traced inputs. By default LSTM uses dimension 1 as batch.

                      Next we load the ONNX model and pass the same inputs

                      import onnxruntime
                      ort_model = onnxruntime.InferenceSession('rnn.onnx')
                      print(ort_model.run(['y'], {'x':X.numpy(), 'c0':c0.numpy(), 'h0':h0.numpy()}))
