配置好 qlib-server服务器,使用 Mac 系统出现 NFS不能正常挂载的故障

🐛 Bug Description

To Reproduce

Steps to reproduce the behavior:

1. 在Mac 系统无法正常完成 NFS 数据挂载

配置文件:

calendar_provider:
    class: LocalCalendarProvider
    kwargs:
        remote: True
feature_provider:
    class: LocalFeatureProvider
    kwargs:
        remote: True
expression_provider: LocalExpressionProvider
instrument_provider: ClientInstrumentProvider
dataset_provider: ClientDatasetProvider
provider: ClientProvider
expression_cache: null
dataset_cache: null
calendar_cache: null

provider_uri: 10.71.117.61:/
mount_path: ./cn_data/
auto_mount: True
flask_server: 10.71.117.61
flask_port: 9710

客户端配置:

import qlib
from qlib.data import D

qlib.init_from_yaml_conf('./config.yaml')
fox = D.calendar(start_time='2010-01-01', end_time='2017-12-31', freq='day')[:2]
print(fox)

Expected Behavior

生成的命令如下: 在 Mac 环境此命令出现未预期的行为
sudo mount.nfs 10.71.117.61:/ cn_data:\'

将 win 改成 windows 问题得以解决

Environment

• Qlib version: '0.9.1.99'
• Python version: Python 3.10.9
• OS (Windows, Linux, MacOS): Mac OS
• Commit number (optional, please provide it if you are using the dev version):

# qlib/config.py : 342 line 
if "win" in platform.system().lower():

fix:
if "windows" in platform.system().lower():

Start at qlib/config.py around line 342, where the platform check controls the generated NFS mount command. Reproduce the issue with the supplied YAML configuration and qlib.init_from_yaml_conf on macOS, then verify that the platform detection produces a valid mount command and that the calendar lookup completes.
