From 446312cd247b95f14be1373d7de6c2b22a96bc5a Mon Sep 17 00:00:00 2001 From: Pietropaolo Frisoni Date: Tue, 17 Sep 2024 11:43:21 -0400 Subject: [PATCH] PennyLane is compatible with JAX 0.4.28 (#6255) **Context:** As part of the effort to make PL compatible with Numpy 2.0 (see #6061), we need to upgrade JAX to 0.4.26+ since such a version introduced the support for Numpy 2.0. We opted for JAX 0.4.28 since it is the same version used by Catalyst. **Description of the Change:** As above. **Benefits:** PL is compatible with Numpy 2.0 and Jax 0.4.28. **Possible Drawbacks:** - From JAX 0.4.27, in `jax.jit`, passing invalid static_argnums or static_argnames now leads to an error rather than a warning. In PL, this breaks every test where we set `shots` in the `QNode` call with `static_argnames=["shots"]`. At this stage, we decided to mark such tests with `pytest.xfail` to allow the upgrade. **Related GitHub Issues:** None. **Related Shortcut Stories**: [sc-61389] --------- Co-authored-by: dwierichs --- .github/workflows/install_deps/action.yml | 4 ++-- doc/releases/changelog-dev.md | 3 +++ .../devices/default_qubit/test_default_qubit.py | 2 ++ .../qutrit_mixed/test_qutrit_mixed_measure.py | 2 +- tests/devices/test_default_qutrit_mixed.py | 2 +- tests/interfaces/test_jax_jit_qnode.py | 17 +++++++++++++++++ .../test_optimization_utils.py | 13 +++++++++++-- 7 files changed, 37 insertions(+), 6 deletions(-) diff --git a/.github/workflows/install_deps/action.yml b/.github/workflows/install_deps/action.yml index 99b77dc8157..e1dc636bb84 100644 --- a/.github/workflows/install_deps/action.yml +++ b/.github/workflows/install_deps/action.yml @@ -15,7 +15,7 @@ inputs: jax_version: description: The version of JAX to install for any job that requires JAX required: false - default: '0.4.23' + default: '0.4.28' install_tensorflow: description: Indicate if TensorFlow should be installed or not required: false @@ -86,7 +86,7 @@ runs: if: inputs.install_jax == 'true' env: JAX_VERSION: ${{ inputs.jax_version != '' && format('=={0}', inputs.jax_version) || '' }} - run: pip install "jax${{ env.JAX_VERSION}}" "jaxlib${{ env.JAX_VERSION }}" scipy~=1.12.0 + run: pip install "jax${{ env.JAX_VERSION}}" "jaxlib${{ env.JAX_VERSION }}" - name: Install additional PIP packages shell: bash diff --git a/doc/releases/changelog-dev.md b/doc/releases/changelog-dev.md index 3f3a3c04326..b03ff7b4f72 100644 --- a/doc/releases/changelog-dev.md +++ b/doc/releases/changelog-dev.md @@ -10,6 +10,9 @@ [(#6061)](https://github.com/PennyLaneAI/pennylane/pull/6061) [(#6258)](https://github.com/PennyLaneAI/pennylane/pull/6258) +* PennyLane is now compatible with Jax 0.4.28. + [(#6255)](https://github.com/PennyLaneAI/pennylane/pull/6255) + * `qml.qchem.excitations` now optionally returns fermionic operators.
