However, this is not the case when PyTorch is installed, but CuPy isn't, so the test would fail. Since this test relies on CuPy, disable it when CuPy is not available. * Fix merge fallout * `CupyOps`: Simplify `asarray` (#661) * `CupyOps`: Simplify `asarray` * Remove `cast_array` flag and use `astype` unconditionally * Revert unconditional call to `astype` * Remove no-op * NumpyOps: Better type-casting in `asarray` (#656) * `NumpyOps`: Better type-casting in `asarray` * Simplify `dtype` check * Update thinc/backends/numpy_ops.pyx Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Simplify casting further, avoid copies if possible * Remove no-op Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Fix out-of-bounds writes in NumpyOps/CupyOps (#664) * Fix out-of-bounds writes in NumpyOps/CupyOps - Using `{CupyOps,NumpyOps}.adam` with incompatible shapes for weights, gradients, or moments resulted in out-of-bound writes. - Using `NumpyOps.adam` with non-float32 arrays resulted filling arrays with incorrect data. * Remove print debugging remnants Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * More print debugging remnants Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Set version to v8.1.0.dev0 (#666) * Fix model.copy() bug where layer used more than once (#659) * Fix model.copy() bug where layer used more than once * Expand functionality to include shims * Corrections after review * Added default for Model._copy() * `conftest.py`: Handle exception caused by `pytest` options being added twice in CI builds (#670) * Auto-format code with `black` + Pin `black` requirement (#673) * Add `autoblack` GitHub action * Fix command * Add `black` to `requirements.txt` * Add support for bot-invoked slow tests (#672) * `Shim`: Fix potential data race when allocated on different threads * Fix two warnings (#676) - torch.nn.functional.sigmoid is deprecated in favor of torch.sigmoid. - Clip cosh input in sechsq to avoid overflow. * Replace use of gpu_is_available with has_cupy_gpu (#675) * Replace use of gpu_is_available with has_cupy_gpu This PR is in preparation of better non-CUDA device support. Once we support non-CUDA GPUs, there may be GPUs available that are not 'CuPy GPUs'. In all places where we use `gpu_is_available` we actually mean: is 'CuPy available with a CUDA GPU'? So, this PR replaces uses of `gpu_is_available` to `has_cupy_gpu`. This allows us to use `gpu_is_available` in the future to check if any GPU is available. In addition to that, some code had expressions like ``` has_cupy and gpu_is_available() ``` This PR simplify such conditions to `has_cupy_gpu`, since `has_cupy_gpu` implies that `has_cupy`. * Remove unused import * Improve error message when no CUDA GPU is found * Fix another error message when no CUDA GPU is found * Fixes for slow tests (#671) * `test_uniqued`: Disable test timing for `test_uniqued_doesnt_change_result` (#678) * `test_to_categorical`: Ensure that `label_smoothing < 0.5` (#680) * `test_to_categorical`: Ensure that `label_smoothing < 0.5` * Use `exclude_max` instead of clamping to `0.49` * test_ops: do not lower precision in conversion to Torch tensor (#681) * test_ops: do not lower precision in conversion to Torch tensor float64 test values close to zero were rounded by conversion to a float32 Torch tensor, resuling in mismatches between Thinc and Torch gradients. This change prevents the loss in precision. * test_ops: compare arrays on same device in Torch comparison * test_maxout: compare arrays with same precision * Add `test_slow_gpu` explosion-bot command * Auto-format code with black (#682) Co-authored-by: explosion-bot <explosion-bot@users.noreply.github.com> * Azure: pin protobuf to fix Tensorflow * Extend typing_extensions to <4.2.0 (#689) * xp2{tensorflow,torch}: convert NumPy arrays using dlpack (#686) * xp2{tensorflow,torch}: convert NumPy arrays using dlpack Newer versions of NumPy can expose arrays as dlpack capsules.

There are various reasons why we should probably move away from using this function: - Upstream will deprecate and remove it: pytorch/pytorch#53124 - We cannot use this mechanism for other devices than CPU/CUDA, such as Metal Performance Shaders. - It offers little flexibility in allocating Torch models on different devices. This PR makes `PyTorchWrapper`/`PyTorchShim` flexible in terms of the devices it can use. Both classes add a `device` argument to their constructors that takes a `torch.device` instance. The shim ensures that the model is on the given device. The wrapper ensures that input tensors are on the correct device, by calling `xp2torch` with the new `device` keyword argument. Even though this approach offers more flexibility, as a default we want to use the `cpu` device when `NumpyOps` is used and `cuda:N` when CupyOps is used. In order to do so, this PR also adds a new function `get_torch_default_device` that returns the correct device for the currently active Ops. `PyTorchWrapper`/`PyTorchShim`/`xp2torch` use this function when `None` is given as the device to fall back on this default, mimicking the behavior from before this PR. * Add some typing fixes * Remove spurious cupy import * Small fixes - Use `torch.cuda.current_device()` to get the current PyTorch CUDA device. - Do not use `torch_set_default_tensor_type` in `set_active_gpu`. * Add `test_slow_gpu` explosion-bot command * Auto-format code with black (#682) Co-authored-by: explosion-bot <explosion-bot@users.noreply.github.com> * Azure: pin protobuf to fix Tensorflow * Extend typing_extensions to <4.2.0 (#689) * Add support for PyTorch Metal Performance Shaders (#685) * Add `test_slow_gpu` explosion-bot command * Auto-format code with black (#682) Co-authored-by: explosion-bot <explosion-bot@users.noreply.github.com> * Add support for PyTorch Metal Performance Shaders Nightly PyTorch versions add support for Metal Performance Shaders (MPS). Metal is a low-level graphics API for Apple platforms that also supports compute kernels (shaders). MPS is a framework of highly-optimized compute and graphics kernels, including kernels for neural networks. MPS is supported on both Apple Silicon, such as the M1 family of SoC, as well as a range of AMD GPUs used in Macs. Since devices are handled in Thinc through a specific `Ops` implementation (e.g. `CupyOps` == CUDA GPUs), this change introduces the `MPSOps` class. This class is a subclass of `NumpyOps` or `AppleOps` (when available). `MPSOps` does not override any methods, but is used to signal to relevant code paths (e.g. `xp2torch`) that Torch tensors should be placed on the MPS device. The mapping in the previously introduced `get_torch_default_device` function is updated to: - `NumpyOps` -> `cpu` - `CupyOps` -> `cuda:N`, where N is the selected CUDA device. - `MPSOps` -> `mps` to ensure placement of Torch tensors on the `mps` device when `MPSOps` is active. Finally, the following booleans have been added to or changed in `compat`: - `has_torch_mps` (new): PyTorch has MPS support - `has_torch_mps_gpu` (new): PyTorch has MPS support and an MPS-capable GPU is available. - `has_torch_cuda_gpu` (new): PyTorch has CUDA support and a CUDA-capable GPU is available. - `has_torch_gpu` (changed): PyTorch has a GPU available (CUDA or MPS). * Test PyTorch wrapper with all xp ops * Azure: pin protobuf to fix Tensorflow * Extend typing_extensions to <4.2.0 (#689) * Fix type checking error * Only back-off to NumpyOps on import error We do not want to hide other issues while importing thinc_apple_ops. * Remove unneeded `has_torch_mps` bool * Add `has_gpu` bool and use it in `util` * Replace another expression by has_gpu * Set `has_torch_gpu` to `has_torch_cuda_gpu` We need to decide whether we want to make the potentially breaking change from `has_torch_cuda_gpu` to `has_torch_cuda_gpu or has_torch_mps_gpu`. But since the latter is not needed for this PR, remove the change. * Update thinc/util.py Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> Co-authored-by: shademe <shadeMe@users.noreply.github.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: explosion-bot <explosion-bot@users.noreply.github.com> Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> Co-authored-by: shademe <shadeMe@users.noreply.github.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: explosion-bot <explosion-bot@users.noreply.github.com> Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> * Expose `get_torch_default_device` through `thinc.api` (#698) * Make `CBlas` methods standalone functions to avoid using vtables (#700) * Make CBlas methods standalone functions to avoid using vtables When testing #696, we found that adding new CBlas methods results in an ABI compatibility. This would mean that every time we add a CBlas method, we also have to rebuild spaCy. The ABI incompatibility occurs because Cython generates a vtable for cdef methods, even when the class or its methods are final. This vtable is used by the caller to look up the (address of) the methods. When methods are added, the vtable of the caller is out-of-sync when the calling code is not recompiled. This change works around this issue by making the methods of CBlas standalone functions. * Add link to PR in comments For future reference. * Add Dockerfile for building the website (#699) * Add Dockerfile for building the website This Dockerfile was taken from spaCy. * README: Remove command substitution in example * Bump version to v8.1.0.dev2 (#701) * Use blis~=0.7.8 (#704) Until the haswell bug is fixed in BLIS v0.9, switch back to blis~=0.7.8. * Set version to v8.1.0.dev3 (#705) * Speed up HashEmbed layer by avoiding large temporary arrays (#696) * Speed up HashEmbed layer by avoiding large temporary arrays The HashEmbed layer sums up keyed embeddings. For instance, a key matrix of the shape (50000, 4) will result in 50,000 embeddings, each computed by summing 4 embeddings. The HashEmbed layer computed the embeddings as follows: vectors[keys].sum(axis=1) where `vectors` is an embedding matrix. However, this way of computing embeddings results in very large allocations. Suppose that `vectors` is (4000, 64). Even though the final embedding matrix is (50000, 64), the first expression will construct a temporary array of shape (50000, 4, 64). This change avoids this by introducing a `gather_add` op as a counterpart to `scatter_add`. In this particular example, the `NumpyOps` implementation only allocates the final (50000, 64) array, computing the embeddings in-place using the BLAS saxpy function. In benchmarks with an M1 Max on de_core_news_lg, this improved processing speed from 40511 WPS to 45591 (12.5% faster). * Simplify saxpy call * Fixup types * NumpyOps.gather_add: add support for double * NumpyOps.gather_add: support int and unsigned int indices * Add gather_add CUDA kernel * Add tests for gather_add * Comment fixup Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> * api-backends: document Ops.gather_add * Ops.gather_add: arguments should be 2D arrays * Comment fix * Ops.gather_add returns Float2d * docs: Ops.gather_add is new in 8.1 Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> * Auto-format code with black (#706) Co-authored-by: explosion-bot <explosion-bot@users.noreply.github.com> * Fix MyPy error when Torch without MPS support is installed (#708) * Check that Torch-verified activations obey `inplace` (#709) And fix some activations that do not obey the `inplace` kwarg. * Increase test deadline to 30 minutes to prevent spurious test failures (#714) * `test_mxnet_wrapper`: Feature-gate GPU test (#717) * Add Ops.reduce_{first,last} plus tests (#710) * Add Ops.reduce_{first,last} plus tests * Add docs for reduce_{first,last} * Typing fix Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> * Typing fixes (use InT) * Fix some some reduction issues when using CuPy * One maxout test fails with the latest CuPy.

MyPy could not infer that code such as the following is correct, ``` def dish(self, X: FloatsType, inplace: bool = False) -> FloatsType: tmp = X * X # ... ``` because the inferred type is the union (or a subtype). If we instead constrain the type variable as follows: ``` FloatsType = TypeVar("FloatsType", Floats1d, Floats2d, Floats3d, Floats4d) ``` the type paramater will be instantiated with a single concrete type, solving such issues. * Remove a bunch of casts and ignores that are not necessary anymore * Unroll `argmax` in `maxout` for small sizes of `P` (#702) * Unroll `argmax` in `maxout` for small sizes of `P` `maxout` uses the `argmax` function to determine the index of the maximum value of each `P` inputs. `argmax` uses a generic array loop, which impedes speculative execution and `could` also prevent unrolling of the outer `maxout` loop. This change unrolls `argmax` with small values of `P` using a variadic template. This leads to a small performance improvement. * Unmodernize struct initialization * Change Docker image tag to thinc-ai (#732) This is purely a cosmetic change, but less confusing than thinc-io :). * Add `with_signpost_interval` layer (#711) * Add with_signpost_interval layer This layer wraps a layer, adding macOS interval signposts for the forward and backward pass.
