Hi dqxcj, Thank you for your feedback. We have tested with our dataset (80k, 32d) and did not encounter this issue. If possible, could you provide the specific parameters you used during the training? Sharing the dataset you used for testing would also be helpful for us to better understand and reproduce the problem.

Hi dqxcj,
We apologize for not being able to reproduce the issue with the parameters you provided. However, we have identified a potential memory corruption issue in the file puck/puck/quantization.cpp
at line 142, where a unique_ptr
is taking ownership of memory allocated by posix_memalign
, which could lead to destructor errors. We are not certain if this is the cause of the problem you're experiencing.
As a result, we have pushed a new branch named fix_mem_corrupt
to address this issue. Could you please check if the problem mentioned in this issue still persists? Thank you for your cooperation.
好的,感谢,我试试

Hi dqxcj,
We have noticed that your log shows:
I1120 17:06:41.142906 589223 puck_index.cpp:867] deviation error of init sub 32 pq codebook clusters is -1
If the nsq parameter is set to 32 and the dataset dimension is 32, there should not be such output for reporting the sub-dimension 32 clustering error. Please provide the complete log information and executed command line, double-check the train/build parameters as well as the dataset to ensure they are valid. This will help us further diagnose the issue.
The relevant code context is located at lines 849 and 867 in the file puck/puck/puck_index.cpp

这次的core是kmeans 收敛不了导致的。一般情况下,kmeans的训练数据集要>= 聚类中心的20倍,且是数据集是dense embedding基本上都会收敛。
有两个办法可以试试, 1.扩大数据规模 or 缩小聚类中心个数。 puck默认coarse & fine聚类中心训练数据规模500w,pq训练规模100w,这种量级下一般都会收敛。如果数据规模太小,可以试试缩小coarse_cluster_count 和 fine_cluster_count,观察一下“kmeans: reassigned”有没有这个报错。pq的训练聚类中心是256,只能扩大训练数据规模试试。 2.上面的办法解决不了的话,大概率是这个数据集分布不太适合kmeans。即使部分时候可以聚类成功,分组效果也会比较差从而导致召回率低。对于这种数据集,推荐使用tinker,设置index_type=2,使用较小的coarse_cluster_count 和 fine_cluster_count。

明白了,这里我的nsq确实设置的不是32,而是33,谢谢。

我尝试将聚类中心个缩小为100,发现还是报错,而且从偶发性变成了必发性,可能确实数据规模太小了或者这个数据集不适合kmeans,或者我的配置有其它错误吗? 配置:

Hi dqxcj,
We have noticed that your log shows:
I1120 17:06:41.142906 589223 puck_index.cpp:867] deviation error of init sub 32 pq codebook clusters is -1
If the nsq parameter is set to 32 and the dataset dimension is 32, there should not be such output for reporting the sub-dimension 32 clustering error. Please provide the complete log information and executed command line, double-check the train/build parameters as well as the dataset to ensure they are valid. This will help us further diagnose the issue.
The relevant code context is located at lines 849 and 867 in the file
puck/puck/puck_index.cpp
.
nsq设置为32仍会报错(index_conf.show()中nsq是33是因为ip2cos=1)

puck支持3种距离计算,分别配置如下: L2 : whether_norm: false COS : 默认 IP : ip2cos (部分数据集支持)
你的配置,看着是期望ip距离。ip2cos,对数据集做了一个转换,用到的是
https://dl.acm.org/doi/pdf/10.5555/3327345.3327382
里的公式(4)。
这个转换在训练之前要做,转换后的数据默认存储在puck_index/all_data.feat.bin,这个时候文件的长度得 = 样本总数 (sizeof(float) (32 + 1)维度 + sizeof(int)) 。 转换的处理可以参考 https://github.com/baidu/puck/blob/0f03b409b259b3791a8c119bfbd769ef73e3e93f/ann-benchmarks/benchmark/algorithms/puck_inmem.py#L86
这个数据集的向量模不满足需求(<1.0),所以没办法直接计算ip距离。只能用cos距离作为近似距离计算,我测试cos是ok的,可以试试修改下参数(设置whether_norm: true,去掉ip2cos: 1) 。
我试着把数据集先按比例缩小,再用ip2cos。filter_nsq = 8 会出core,filter_nsq=6是ok的。应该是一些边界条件没做检查,需要定位一下问题&修复一下bug。

这里我用的确实有点迷糊,有些问题想请教一下:
static int IP2L2Convert(const std::vector<float>& org, std::vector<float>& convert, const ConvertParam& param) {
convert = org;
if (param.query_flag) { // query向量处理
convert.emplace_back(0.0);
} else { // item向量处理
convert.emplace_back(sqrt(param.max_phi_square - Square(org)));
}
return 0;
}
- 使用IP距离时,如果提前将数据进行了L2归一化处理,那puck是否应该设置为L2距离? 如果向量是归一的,ip距离和cos距离是等价的,距离值是一样的。 这个时候,设置whether_norm = true,默认也是true。不需要额外设置其他的。返回的距离是2-2cos。
2. 使用IP距离时,如果提前将数据按照https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/XboxInnerProduct.pdf 中的Theorem 1进行处理,那puck应该如何设置距离度量方式?代码实现如下:
提前做转换,对于puck来说,他处理的是转换后的32+1维的数据集,不知道32维数据集的存在。 这个数据集上要用ip2cos,还是要满足32+1维特征的模<1.0,在这个数据集上是不满足的,所以没办法用ip距离,建议用cos距离作为近似距离返回。 假如说,Theorem 1转换后,满足32+1维特征的模<1.0,需要设置ip2cos=1,返回距离2-2ip。
32维数据集的暴力搜索结果与32+1暴力结果有diff,是Theorem 1导致的。puck的理想召回结果是32+1的暴力。
好嘞,我消化一下,非常感谢两位大佬的帮忙

已修,推在分支fix_mem_corrupt
。这个bug会出现在当dim
不被nsq
整除的情况。
在@nk2014yjdim=33
数据集的例子中,nsq=8
时的lsq=5
,此时PQ的子空间维度为[5, 5, 5, 5, 5, 5, 3, 0],在处理0维度子空间的时候出现多余的内存复制导致overflow;但在nsq=6, lsq=6
的情况下,PQ子空间维度为[6, 6, 6, 6, 6, 3]不存在0维度子空间所以可以正常执行。
麻烦请重新测试代码以验证问题是否解决,谢谢。

bug表现
在测试puck过程中发现一个偶发性bug,表现如下面两张图
gdb调试发现是puck::PuckIndex::train: 795的
std::unique_ptr<float[]> kmeans_train_vocab(new float[train_vocab_len]);
在释放时报的错:怀疑是往kmeans_train_vocab填充数据时内存越界了,导致train结束释放kmeans_train_vocab时出现问题。
在复现时发现,召回率不理想的小数据集(80k行,32维,top300召回率10%)出现这个bug的概率较高(大数据集跑起来太慢,没咋测试)
