Web20 mrt. 2024 · Basic Linear Algebra Subprograms (BLAS)는 벡터 덧셈, 스칼라 곱셈, 닷프로덕트, 선형 조합, 행렬 곱셈등의 일반적인 선형대수 연산을 수행하는 로우레벨 루틴 집합을 명세한 규약임. BLAS는 선형대수 라이브러리들을 위한 로우레벨 루틴의 사실상 표준으로, c와 포트란 버젼 모두에 바인딩된 버젼이 있음. 물론 BLAS 규약이 일반적이지만, … WebTo specify MKL-powered NumPy in a non-ambiguous way, you can specify the mutex package (either directly or indirectly): conda install numpy “blas=*=mkl” There is a simpler way to address this, however. For example, you may want to try another package that has the desired mutex package as a dependency. nerdist wheel of time episode 5
