input is a 2-D tensor, newvalue is a 1-D tensor,

I just want to implement a simple assignment, for example `input[0]=newvalue`

.

```
def func(state ..):
index = te.var("index")
newvalue = te.compute(...)
..
# TypeError: 'Tensor' object does not support item assignment
state[index] = newvalue
..
# SyntaxError: expression cannot contain assignment, perhaps you meant "=="?
_ = te.compute((1024), lambda i: state[5*index][i] = newvalue[i])
```

It is really hard for new beginner, any body can help me?
