<p>对输入张量进行步长切片（Strided Slice）操作。该算子根据起始位置（begins）、结束位置（ends）和步长（strides）从输入张量中提取子张量。该算子不区分数据类型，适用于所有数据类型。</p>
|
||
<p>算法支持三种运行模式：
|
||
1. <strong>全拷贝模式**（soft_copy_mode = 1）：当输出是输入的连续子区域时，使用内存拷贝。
|
||
2. **快速运行模式**（fast_run = 1）：优化的快速路径，适用于特定场景。
|
||
3. **普通模式</strong>：逐块拷贝模式，适用于一般情况。</p>
|
||
<p>对于每个维度 <cite>i</cite>，输出张量的索引范围由 <cite>begins[i]</cite>、<cite>ends[i]</cite> 和 <cite>strides[i]</cite> 决定：</p>

<div class="math notranslate nohighlight">
