设置号 操作系统：ubuntu 18.04 LTS
适用于Linux（x86_64）的MySQL版本14.14 Distrib 5.7.26，使用EditLine包装器
（还安装了以下依赖项： sudo apt-get安装libmysqlclient-dev sudo pip3安装mysqlclient 康达安装-c anaconda sqlalchemy ）
Python 3.7.3
我遵循的步骤
在那里创建的数据库名为＃mlflow_tracker
现在我尝试以“
”启动MlFlow服务器(base) asraful@asraful:~$ conda activate my_env
(my_env) asraful@asraful:~$ mlflow server --backend-store-uri "mysql://mlflow:password@localhost:3306/mlflow_tracker" --default-artifact-root /mnt/mlflow_bucket --host 0.0.0.0
这将输出显示为＃
[2019-05-14 01:49:56 +0600] [9976] [INFO] Starting gunicorn 19.9.0
[2019-05-14 01:49:56 +0600] [9976] [INFO] Listening at: http://0.0.0.0:5000 (9976)
[2019-05-14 01:49:56 +0600] [9976] [INFO] Using worker: sync

[2019-05-14 01:49:56 +0600] [9989] [INFO] Booting worker with pid: 9989
因此，我尝试使用波纹管脚本＃
进行一次测试import os
from mlflow import log_metric, log_param, log_artifact
if __name__ == "__main__":
# Log a parameter (key-value pair)
log_param("param1", 5)
# Log a metric; metrics can be updated throughout the run
log_metric("foo", 1)
log_metric("foo", 2)
log_metric("foo", 3)
# Log an artifact (output file)
with open("output.txt", "w") as f:
f.write("Hello world!")
log_artifact("output.txt")
此代码运行完美。
因此，我的期望是：
指标将保存在mlflow_tracker数据库中。 其他数据将保存在/ mnt / mlflow_bucket
下我将 backend-store-uri配置为：mlflow_tracker数据库 还有 default-artifact-root：/ mnt / mlflow_bucket
但是遇到＃
问题
所有指标和元数据都在默认mlflow位置下写入： /〜/ mlFlow / mlruns / 0
而且，如果我尝试从浏览器访问mlflow ui，则获得了默认图像和波纹管堆栈跟踪。

我的问题是：
我在这里缺少什么？对此可能有什么解决方案？
