conda虚拟环境运行产生core dump

在conda中运行kallisto出现非法指令（核心已转储），ulimit -c unlimited 已经打开，core储存位置以更改至当前目录下，为啥找不到coredump呀

root@ubuntu-virtual-machine:/home/ubuntu# cat /proc/sys/kernel/core_pattern

“core-%e-%p-%t”

-----------------------------

(kallisto) ubuntu@ubuntu-virtual-machine:~$ kallisto index /home/ubuntu/gene/test1/Homo_sapiens.GRCh38.cdna.all.fa.gz -i Homo_sapiens.GRCh38.cdna.all.index

非法指令 (核心已转储)
