我试图从Google重现project to predict the results of the 2014 world cup。 （ipython-soccer预测）
我正在浏览该链接的“如何部署”部分。在这条线出现之前，一切都是正常的
sudo docker run -p 8888:8888 fhoffa/ipython-predictions:v1
运行此代码会给我以下结果
2015-07-16 17:00:24,514 INFO spawned: 'sshd' with pid 10

所以我认为这个问题与gitpull-predictions有关。然后我查看了名为gitpull-predictions-stderr---supervisor-KmqU8Z.log的日志文件，其中包含：
fatal: destination path '/home/ipy/ipynotebooks/soccer' already exists and is not an empty directory.
fatal: destination path '/home/ipy/ipynotebooks/soccer' already exists and is not an empty directory.
fatal: destination path '/home/ipy/ipynotebooks/soccer' already exists and is not an empty directory.
在运行/home/ipy/ipynotebooks/soccer之前，目录docker run不存在，但是运行代码会出现此错误。
然后我查找名为'supervisord-extra.conf'的配置文件。 在这个文件中它说
[program:gitpull-predictions]
command=/usr/bin/git clone https://github.com/GoogleCloudPlatform/ipython-soccer-predictions.git /home/ipy/ipynotebooks/soccer
所以我认为这个'gitpull-predictions'从给出/ home / ipy / ipynotebooks / soccer目录的地址做'git clone'。但我认为这个命令'git clone'不仅运行了一次，而且甚至在它将文件克隆到目录后很多次。因此'/ home / ipy / ipynotebooks / soccer'在'docker run'命令之后存在，但随后'git clone'运行多次给出'致命目的地'错误。
接下来我做的是编辑配置文件，如下面的
[program:gitpull-predictions]
startsecs = 0
autorestart = false
command=/usr/bin/git clone https://github.com/GoogleCloudPlatform/ipython-soccer-predictions.git /home/ipy/ipynotebooks/soccer
我添加了这两行，startsecs = 0和autorestart = false。 当我再次运行'docker run'时，消息显示

还有gitpull-predictions退出（未预料到） 然后我查看了显示的错误日志
Cloning into 'ipython-soccer-predictions'...
仍然没有成功运行。有什么解决方案吗？ 我开始想知道为什么'git clone'用于名为'gitpull'的程序。该计划的名称应该是'gitclone'......
