Description

在embedding训练中增加inf_cl_loss，在超大batch_size下能有效节省显存消耗。

经测试，inf-cl算子能够与原有损失函数有效对齐：

• 以数据类型设置bf16，group_size设置1，gradient_accumulation_steps设置4为例，inf_cl_loss与原有contrastive_loss的收敛曲线如下：
  

经测试，在超大batch_size下，inf-cl算子能够有效降低embedding训练时的显存消耗：

• 在8张A100（80G）显卡下，以数据类型设置bf16，group_size设置4，gradient_accumulation_steps设置4096为例，inf_cl_loss与原有contrastive_loss的显存占用对比如下：

不使用inf-cl；embedding_negatives_cross_device=True	超出显存限制

这个没有默认安装,需要 try except一下

你把import 的代码放到这里吧, 然后没有包的话，直接报错。

try:
    from paddlenlp_kernel.triton.inf_cl import cal_inf_loss
except ImportError:
    logger.warning(
        "Paddlenlp_kernels are not available, which means the inf_cl loss cannot be used. If you wish to use the inf_cl loss, please follow the instructions in the README.md on the `ops`."
