[Question] Hitting Weird Error #527

Open ChaoGaoUCR opened 5 months ago

ChaoGaoUCR commented 5 months ago

I ran the scripts and hit an error that doesn't even enter the program, I wondered if anyone had the same issues before, more weird thing is this error doesn't occur on my other machine..... Both are Ubuntu 20.04

Scripts I use: build/apps/build_memory_index --data_type float --dist_fn l2 --data_path $siftsmall/siftsmall_base.bin --index_path_prefix $siftsmall/siftsmall_R32_L50_filtered_index -R 32 --FilteredLbuild 50 --alpha 1.2 --label_file $siftsmall/rand_labels_50_10K.txt --universal_label 0

Similar error (src/tcmalloc.cc:284] Attempt to free invalid pointer 0xd66f32bd0 ) when I ran ./apps/build_disk_index --data_type uint8 --dist_fn l2 --data_path /OPTANE/sift1b/base.1B.u8bin --index_path_prefix $modelpath/diskann_sift1b_base/sift1b_R64_L100_B8.1_M64_PQ12 -B 8.1 -M 64 --build_PQ_bytes 12
