我需要一些帮助来解决此错误：
ERROR: Cannot install -r requirements.txt (line 7) and urllib3==1.26.5 because these package versions have conflicting dependencies.
The conflict is caused by:
The user requested urllib3==1.26.5
botocore 1.13.50 depends on urllib3<1.26 and >=1.20; python_version >= "3.4"
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
它说 botocore 和 urllib3 之间不兼容，但不确定需要什么版本。
