ATen/JIT Function Schema

This doc is to talk about the difference in ATen/JIT function schema and find a way to align each other.

List syntax

Currently in ATen function schema when we want to define a list, we have:

wanchaol

import torch

class Test(torch.jit.ScriptModule):
  def __init__(self, b = None):
    self.b = b
  def forward(self, input):
    x = input
    if self.b is not None:
      x = self.b(input)
      

wanchaol

import torch


def fn(input):
    return torch.log(input + 1e-8)


input = torch.rand(5, 5)

output = fn(input)

wanchaol

import torch
import torch.nn as nn
import torch.nn.functional as F


class LeNet(nn.Module):

    def __init__(self):
        super(LeNet, self).__init__()
        # 1 input image channel, 6 output channels, 5x5 square convolution

wanchaol

import torch

def remove_sentence_boundary(tensor):
    tensor_shape = list(tensor.data.shape)
    new_shape = list(tensor_shape)
    new_shape[1] = tensor_shape[1] - 2
    tensor_without_boundary_tokens = torch.zeros(new_shape, device=tensor.device)
    return tensor_without_boundary_tokens

traced_fn = torch.jit.trace(remove_sentence_boundary, torch.rand(10, 20, 30))

a = torch.tensor([[-0.5689,  1.3550, -1.7742, -0.2412,  0.2400],
    [-1.1720,  0.6153,  0.0285,  0.7397,  0.3760],
