"ndarray" and "autograd::ndarray"

Hi, i am a beginner of this interesting rust deep learning library.
When i try to run several basic examples using ndarray
, i found that always has a compiler error saying i should use autograd::ndarray
. Code and error are shown as follow:
ag::with(|g| {
let x = g.placeholder(&[-1,-1]);
let value = array![[1., 1.]];
println!("{:?}", x.eval(&[x.given(value.view())]).unwrap());
});
error[E0308]: mismatched types
--> src\main.rs:14:43
|
14 | println!("{:?}", x.eval(&[x.given(value.view())]).unwrap());
| ^^^^^^^^^^^^ expected struct `autograd::ndarray::ArrayBase`, found struct `ndarray::ArrayBase`
|
= note: expected struct `autograd::ndarray::ArrayBase<autograd::ndarray::ViewRepr<&_>, _>`
found struct `ndarray::ArrayBase<ndarray::ViewRepr<&{float}>, ndarray::Dim<[usize; 2]>>`
= note: perhaps two different versions of crate `ndarray` are being used?
Is that compulsory to use ag::ndarray::array![[1., 1.]]
instead of array![[1., 1.]]
in this kind of cases?
Thanks for your help.

Okay, i found that happens because i used the version 0.15.1
of ndarray
.
After i changed the dependence version to 0.12.1
everything works.

Thank you for the report, yes, ndarray
is re-exported to avoid this problem for now.
