Convert a numpy float16 data to hex string importnumpyasnp a=np.float16('1.125')a_hex=hex(a.view(np.int16)) Remember to view any float format as int befort you hex them. This way you could get the same hex value asnp.to_file(a). Convert a hex string to numpy float16 data im...

虽然默认数据类型是浮点数(np.float64),您可以明确指定想要的数据类型,使用dtype关键字。 代码语言:javascript 复制 >>> x = np.ones(2, dtype=np.int64) >>> x array([1, 1]) 在这里了解更多关于创建数组的信息 添加、删除和排序元素 这个部分涵盖 np.sort(),np.concatenate() 使用np.sort()简单地...
