PyTensor
Tensor expression graphs, automatic differentiation, and compilation for numerical computation.
External resource. No execution or independent verification is claimed here.
Do automatic gradients match analytic derivatives across a fixed grid of nonsingular inputs?
Derive scalar components independently, compare with frozen tolerances and dtypes, and inspect nondifferentiable boundary cases separately.
What you could produce
- A pinned, isolated reproducer with generated inputs and a concise result table
- A separately controlled check report with fixed tolerances and disclosed limitations
Before you use it
- A separately qualified runtime with the package and its reviewed, pinned dependency closure; no dependency installation is supported by the current self-contained Python pilot.
Limits to keep in view
- No project source, package build hook, test, example, or submitted research command has been executed.
- The documented pilot supports self-contained Python 3.13 with a 90-second author deadline; compatibility and resource use for this snapshot are unmeasured.

Approved for catalog metadata and links. The displayed entry identifies PyTensor with the concise collection-authored summary “Tensor expression graphs, automatic differentiation, and compilation for numerical computation.” and points to the public upstream repository https://github.com/pymc-devs/pytensor. The wording describes function and possible investigation without reproducing upstream source or documentation, claiming execution, or implying endorsement or rights beyond the recorded scopes.

Inspect the license evidence ↗Before copying source material
- Bundled datasets, examples, submodules, vendored code, and dependency licenses have not been audited; the observed top-level license does not clear all of them.
- README and documentation rights were not independently resolved from the main code license; this catalog only links and describes.
- The apparent root LICENSE.txt is a textual link target; doc/LICENSE.txt is the actual fetched license. Its named inherited-code notices must be retained.
