range的范围
for i in range(0, num_shots, batch_size):
在 for
循环中,range(0, num_shots, batch_size)
的参数含义如下:
0
: 起始值,表示从索引 0 开始。num_shots
: 结束值,表示循环到num_shots
为止(不包括num_shots
)。batch_size
: 步长,表示每次循环的增量,即每次循环处理的批次大小。
这个循环的作用是以 batch_size
为步长遍历从 0 到 num_shots
的范围。
从list中提取元素子集
i:i + batch_size
is a Python slice notation used to extract a subset of elements from a list. In this context, it is used to get a batch of elements from the list camera_targets
starting at index i
and ending at i + batch_size
.
Here’s a brief explanation:
i
is the starting index of the slice.i + batch_size
is the ending index of the slice (exclusive).
For example, if i
is 0 and batch_size
is 3, camera_targets[0:3]
will return the first three elements of the camera_targets
list.
