我们从训练集中检索的每个样本都包含一个张量的图像数据和相应的张量标签。 由于样本是一个序列类型([sequence type](https://docs.python.org/3/library/stdtypes.html#typesseq)),我们可以使用序列解压( *sequence unpacking* )来分配图像和标签。现在我们将检查图像的类型和标签,看看他们都是 torch.Tensor 对象:...

Xarray introduces labels in the form of dimensions, coordinates and attributes on top of raw NumPy-like arrays, which allows for a more intuitive, more concise, and less error-prone developer experience. The package includes a large and growing library of domain-agnostic functions for advanced ...
如果要使用R包,可以使用library()函数,首先载入包,也可使用require函数来加载包,这时候就不需要使用引号了,因为R包已经安装好了,系统中已经包含这个关键字了 R软件本身也是有几个独立的包构成的,R软件本身包括:base、datasets、utils、grDevices、graphics、stats、methods、splines、stats4、tcltk。它们提供了种类繁多...
RockHound is a Python library to download geophysical models and datasets (PREM, CRUST1.0, ETOPO1) and load them into Python data structures (pandas, numpy, xarray). Many of these models use non-conventional file formats or can be tricky to find on the internet. RockHound knows how to dow...
datasets = list_datasets() print("Number of datasets in the Datasets library: ", len(datasets), "\n\n") #list of datasets in pretty-print format pprint(datasets, compact=True) 如果在下载数据集之前就想知道它的属性,该怎么办呢?我们可以使用一行代码来实现这一点。☝️只需将索引设置为数据...
