CuPy v7.8.0 をリリースしました！ リリースノートは以下の通りです。


This is the release note of v7.8.0. See here for the complete list of solved issues and merged PRs.

Highlights

  • This release adds support for CUDA 11, NumPy 1.19, and SciPy 1.5.
  • We expect this version to be the final release for v7.x series. Please start testing your workloads with the latest v8.x pre-release.

Notes on CUDA 11.0 support

  • cupy-cuda110 wheel packages are currently available only for Windows. We are going to publish Linux wheels once we got approval from PyPI team.
  • cupy-cuda110 packages are built with cuDNN support but without bundled cuDNN shared libraries (see #3724 for the discussion). To use cuDNN features, you need to install cuDNN v8.0.x via the system package manager (e.g, apt install libcudnn8 or yum install libcudnn8) or manually install it and set LD_LIBRARY_PATH (Linux) or PATH (Windows) environment variables.
  • When building CuPy from source with CUDA 11.0, g++-6 or later is required. See the installation guide for the detailed instructions.
