未曾老师，这个在执行命令行出现乱码
url_template: "https://ids.si.edu/ids/viewTile/node2/A/391/391bde0966204b9b3874902eaadd90a6/512/13/{{x/256}}_{{y/256}}.jpg"
variables:
- name: x
from: 0
to: 4200 # Image width, taken from stage 1
step: 256 # Tile width, taken from stage 1
- name: y
from: 0
to: 2640 # Image height
step: 256 # Tile height
请问构成yaml的有什么问题吗，再一个就是，这图有很多段，能否一次下载
