在Docker容器中发送图片失败

[Leo-455]

我想实现的功能是从网络上接收信息，将其处理成一张图片后存储在与插件同目录的一个文件夹中，之后发送。
下面是我的代码：

from nonebot import on_command, get_bot, logger
from nonebot.adapters.onebot.v11 import MessageSegment

from datetime import datetime
from pathlib import Path

from obspy.imaging.beachball import beachball

cmt = on_command("CMT")
@cmt.handle()
async def get_cmt():
    pass

    cmt_photo_dir = Path(__file__).parent / "CMT_Photos"
    cmt_photo_path = cmt_photo_dir / f"CENC CMT {eq_time}.png"
    logger.success(cmt_photo_path)
    beachball(f1, size=200, linewidth=2, facecolor='r',
              outfile=cmt_photo_path)

    cmt_photo_path = cmt_photo_path.as_uri()
    logger.success(cmt_photo_path)
    msg = f"{type}\n{output}" + MessageSegment.image(cmt_photo_path)

    bot = get_bot()
    await bot.send_msg_rate_limited(
        message_type="private",
        user_id=pass,
        message=msg
    )

其中beachball函数会生成一张图片并保存。
这部分代码在Windows上使用nb run直接运行时消息可以正常发出，但使用nb docker up在docker容器中运行时发生错误
下面是错误报告：

我检查了docker发现这个文件被正常的保存在docker中了，
但是不知道为什么最后发送的时候文件路径却出了问题，到C:\\Program Files\\Tencent\\QQNT\\下去找这个文件了，而本来应该在docker中寻找的。
求大佬解答，非常感谢

如果你是使用路径来发送图片的，那是协议端来根据路径寻找图片。所以，不管你的机器人是不是在容器内，都是在协议端主机路径找图片。

了解了，感谢

已解决，docker需要做一下路径映射。
