Notes --- Training logs are represented as a nested set of dictionaries with the following structure: log[model_id][metric][trial_number][duplicate_number] For example, ``logs['model1']['regret'][3][1]`` holds the regret value accrued on the 3rd trial of the 2nd duplicate run for m...
in1d:(M,) ndarray, bool 值ar1[in1d]在ar2中。 Notes 对于1-D序列,in1d可被视为python关键字in的逐元素函数版本。in1d(a,b)大致等同于np.array([item in b for item ina])。 但是,如果ar2是一个集合或类似的(非序列)容器,则此方法将失败:ar2被转换为数组,在这种情况下为asarray( ar2)是一个...

NumPy(Numerical Python)是 Python 中的一个线性代数库,在数组矩阵运算、逻辑运算以及Scikit-learn、pandas和tensorflow等包中被大量使用> NumPy的主要对象是同种元素的多维数组。这是一个所有的元素都是一种类型、通过一个正整数元组索引的元素表格(通常是元素是数字)。在NumPy中维度(dimensions)叫做轴(axes),轴的个...
CuPy is a NumPy/SciPy-compatible array library for GPU-accelerated computing with Python. CuPy acts as a drop-in replacement to run existing NumPy/SciPy code on NVIDIA CUDA or AMD ROCm platforms. >>> import cupy as cp >>> x = cp.arange(6).reshape(2, 3).astype('f') >>> x array...
This book offers readers a quick, thorough grounding in knowledge of the Python open source extension SciPy. The SciPy library, accompanied by its interdependent NumPy, offers Python programmers advanced functions that work with arrays and matrices. Computational Physics with Python (Eric Ayars) Thi...
