请问模型启动一半卡住，是什么问题？

使用的是./main -m zh-models/7B/ggml-model-q4_0.bin --color -f prompts/alpaca.txt -ins -c 2048 --temp 0.2 -n 256 --repeat_penalty 1.3这个命令，输出就卡在a这个地方，也没办法进行交互

嗯，有的时候是会这样，回车一下有时会解决。
另外，看你的log应该是上一版的llama.cpp，可以pull一下最新版重新编译试试，个人感觉启动比之前一版流畅一些。

更新了llama.cpp之后确实可以跑起来了，但是生成速度非常慢，可能5-10Min生成1个字，这是正常的情况吗？比如下面是运行了20分钟之后的结果

看一下这个#51

[YukinoshitaKaren]

我尝试了一下，速度还是很慢，请问程序是不是没有调用我的显卡，导致速度慢呢

llama.cpp不会调用GPU。如果是mac M系列芯片会比较快。
另外可以通过增加-b（batch size）和-t（线程数）来提速（实测不是很明显）。

[YulongXia]

我的系统是Linux debian 5.10.0-20-amd64 #1 SMP Debian 5.10.158-2 (2022-12-13) x86_64
在使用llama.cpp量化了模型，得到zh-models/7B/ggml-model-q4_0.bin，
此时使用main进行预测，非常慢！！！！！
./main -m zh-models/7B/ggml-model-f16.bin --color -f prompts/alpaca.txt -ins -c 2048 --temp 0.2 -n 256 -b 2048 --repeat_penalty 1.3

我使用-b指定了batch_size=2048，但输出的日志显示仍然是512，同时main的默认线程数是4，但是从输出日志来看，默认并不是4，而是将所有核都沾满(56/56)。
然后我显式指定了线程数4，程序就不再卡顿了
