No module named sniffles2_plot

[Mars-fi]

I found a problem in using this package on Elastic Compute Service, below is my code:

Code:
module load apps/anaconda3/23.1.0
source activate /public/home/xxx/miniconda3/envs/env_2
python3 -m sniffles2_plot -i /public/home/xxx/Data/input.vcf -o /public/home/xxx/Output/

Then it showed /public/software/apps/anaconda3/bin/python: No module named sniffles2_plot

But I use pip list, and I can see sniffles2_plot 0.2.1,
Then I install again, it showed: Requirement already satisfied: sniffles2-plot in ./miniconda3/envs/env_2/lib/python3.10/site-packages (0.2.1)

How can I solve this problem?
