问题描述
我正在尝试使用名为 azureml-sdk-for-r 的 R 包。它在底层使用 Python 并创建一个 docker 映像，最终在 Azure 中运行 Web 服务。在这种情况下，它是在本地部署的。我的评分脚本 score1.R 与运行此脚本的文件夹位于同一文件夹中：
library(azuremlsdk)
interactive_auth <- interactive_login_authentication(tenant_id="296bf094-bdb4-488f-8ebd-92b2dd1464c2")
ws <- get_workspace(
name = "xxx",subscription_id = "xxx",resource_group ="xxx",auth = interactive_auth
)
model <- get_model(ws,name = "iris")
r_env <- r_environment(name = "r_env")
# Create inference config
inference_config <- inference_config(
entry_script = "score1.R",source_directory = ".",environment = r_env)
local_deployment_config <- local_webservice_deployment_config()
service <- deploy_model(ws,'rservice-local',list(model),inference_config,local_deployment_config)
# Wait for deployment
wait_for_deployment(service,show_output = TRUE)
# Show the port of local service
message(service$port)
主要问题似乎是这个（见下面更长的输出）：
cannot open file '/var/azureml-app/iris/score1.R': No such file or directory
我需要在本地创建这个文件夹吗？它看起来像一个 Unix/Linux 文件夹，但我在 Windows 中工作。任何输入将不胜感激。谢谢！
