Struct EagerNoGradGuard 

pub struct EagerNoGradGuard { /* private fields */ }

Scope guard that temporarily disables eager operation recording.

Values computed while this guard is alive are concrete eager tensors, but they do not participate in reverse-mode gradient tracking.

Examples

use tenferro_ad::{EagerRuntime, EagerTensor, Tensor};
use tenferro_cpu::CpuBackend;

let ctx = EagerRuntime::with_cpu_backend(CpuBackend::new());
let x = EagerTensor::requires_grad_in(
    Tensor::from_vec_col_major(vec![1], vec![2.0_f64]).unwrap(),
    ctx.clone(),
)?;
let y = {
    let _guard = ctx.no_grad();
    x.mul(&x)?
};
assert!(!y.tracks_grad());

Trait Implementations

impl Debug for EagerNoGradGuard

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for EagerNoGradGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
