我正在尝试使用https://docker-py.readthedocs.io/en/stable/index.html制作一个Python脚本，该脚本运行我的容器。
安装软件包后(使用import docker导入，我的图像称为" Janus"(，这是我的Python脚本：
import docker
client = docker.from_env()
client.containers.run("janus")
运行脚本时，我会得到
Traceback (most recent call last):
File "/home/milanlakhani/.local/lib/python3.6/site-packages/requests/packages/urllib3/util/timeout.py", line 124, in _validate_timeout
float(value)
TypeError: float() argument must be a string or a number, not 'Timeout'
During handling of the above exception, another exception occurred:

也许我错过了一些非常明显的东西，因为我是初学者，但是在Docker-Py文档中，我看不出为什么这不起作用。(我认为我不需要设置环境变量，例如 DOCKER_HOST， DOCKER_TLS_VERIFY， DOCKER_CERT_PATH，因为据我所知，我以正常方式在计算机上运行docker。(
请告诉我，如果您需要更多详细信息，我还可以发送用于构建图像的Dockerfile，该图像公开端口并具有命令
CMD /usr/bin/janus -o --configs-folder=/usr/local/share/ct-camera/janus
但是，我尝试了其他图像和图像名称，其中包括存储库，而无论图像如何，错误始终是相同的！
我还尝试了此软件包中的其他命令，但也发生了同样的事情。
我认为您需要提供正确的图像名称 - 像：
client.containers.run("myrepo.com/janus")
并确保拥有最新的requests软件包：
pip3 install -U requests
使用pip3 uninstall requests和pip3 install requests==2.15将我的请求软件包的版本从2.22降低到2.15，解决了此问题。
