我正在尝试在 docker 环境中运行 MLProject 后将指标和工件存储在主机上。我期望当实验成功完成时，mlruns/ 文件夹中的工件、指标文件夹应该具有值并显示在 mlflow ui 上，但工件、指标文件夹在 mlruns/ 文件夹中是空的。mlflow ui 也没有反映新的实验。

/home/mlflow_demo/mlflow-demo.py -

import mlflow
from mlflow.tracking import MlflowClient
from random import random
import pickle

client = MlflowClient()
experiment_id = client.create_experiment(name='first experiment')
run = client.create_run(experiment_id=experiment_id)
for i in range(1000):
 client.log_metric(run.info.run_id,"foo",random(),step=i)
with open("test.txt","w") as f:
 f.write("This is an artifact file")
client.log_artifact(run.info.run_id,"test.txt")
client.set_terminated(run.info.run_id)

/home/mlflow_demo/MLProject -

name: test-project
docker_env:
 image: kusur/apex-pytorch-image:latest
entry_points:
 main:
  command: "python mlflow-demo.py"

命令（在 /home/mlflow_demo 中执行）： -mlflow run .

运行上述代码后，我得到以下日志 -

有人可以提供指点。如果问题没有很好地提出，请告诉我。

您已将代码发布为

for i in range(1000):
client.log_metric(run.info.run_id,"foo",random(),step=i)

应该是这样的

for i in range(1000):
    client.log_metric(run.info.run_id,"foo",random(),step=i)

同样是没有缩进的情况

with open("test.txt","w") as f:

你能用正确的python缩进更新代码并重新运行吗
