The above problem solved by modifying the model code.
However, another problem occurred when inferring the type of intermediate
tensor and there is a `type cast` operator.
sample code to reproduce the error.
```
import torch
import tvm
from tvm import relay
import tvm.contrib.graph_runtime as runtime
def fn(x):
y = (x != 0).long()
y = y.to(dtype=torch.float32)
y = y[:, 0]
return y
jit = torch.jit.trace(fn, (torch.ones(4, 5, dtype=torch.int64),))
torch.jit.save(jit, "test.jit")
jit = torch.jit.load("test.jit", map_location=torch.device('cpu'))
jit.eval()
print(jit(torch.ones(4, 5, dtype=torch.int64)))
batch = 1
seq_length = 43
shape_list = [('input', [4, 5])]
input_types = [('input', 'torch.int64')]
print("==========relay=======")
#print(jit.code)
mod, params = relay.frontend.pytorch.from_pytorch(jit,
shape_list,
input_types=input_types,
// Add input types, or input type only could be float32
default_dtype="float32")
```
