非常感谢您的回复!我想再次询问关于使用管道的问题,即遍历自己的测试集并通过批处理输入到管道中。但我在后续迭代中发现了一个错误:Deadlock detected. Resetting KV cache and recomputing requests. Consider limiting number of concurrent requests or Consider limiting number of concurrent requests or decreasing max lengths of prompts/generations. 这是上一次迭代中使用的kvcache没有正确释放的原因吗?我应该如何正确使用非持久模式以充分利用此框架的性能?@mrwyattii

死锁可以在持久模式和非持久模式下发生。在将请求放在推理引擎之前,我们不会检查是否有足够的内存来计算每个请求生成的所有潜在令牌。这是出于性能原因,但如果请求过多,我们就会陷入这种死锁场景(阅读更多关于此的评论)。

我们正在努力改进,以便用户能够更好地调整推理引擎的行为,以避免给定用例中的死锁。

使用持久部署的一个好处是,您可以定期发送请求,而不是一次性全部发送。例如,如果您有50个请求...使用非持久管道并将它们全部批量发送 response = pipeline(my_50_requests) 可能会导致死锁。使用持久部署,您可以有许多客户端,每个客户端在时间上略有不同地发送子批次。这就是我们在基准测试中所做的第二种情况,因为它更接近于“现实世界”的服务场景。

持久部署还具有更快响应请求的优点。使用非持久管道,您必须等待所有50个请求完成后才能收到任何响应。但是有了多个客户端,您会很快得到第一个响应。

请让我知道是否需要进一步澄清!

非常感谢您耐心而详细的回复!关于非持久模式的主要问题如下:

您可以看到,在前几个循环中,响应正常返回,但随后出现了死锁,因此我怀疑在前几个循环中使用的kvcache没有正常释放。这对我来说只是一个小问题,我正在尝试持久模式,从尝试基准代码来看应该没问题。然后我还想再次询问这个框架是否支持闪存解码,甚至闪存解码++,我非常期待将这个算法添加到这个框架中! @mrwyattii

请查看为什么会出现这个问题,我正在尝试在持久模式下测试自己的数据,但在预热阶段出现了错误:

@mrwyattii 您的帮助非常需要,使用持久化并没有非常顺利,为什么当我在自己的数据集上运行时,总是会出现GPU不再被利用的情况,但程序从未执行,也没有报告错误。我应该如何正确使用非持久化模式?

你好,Traveller2001。抱歉回复晚了,过去两周我一直不在办公室。你能在没有你这里指定的更改的情况下运行基准测试吗?我会尝试重现结果,但Tohtana可能能提供更好的帮助,因为他们编写了基准测试代码。
