visdom-wrapper的Python项目详细描述
visdom包装器
在python“with”语句中使用visdom的包装器。
设置
pip3 install visdom-wrapper
示例
import numpy as np
import time
import os.path
import getpass
from sys import platform as _platform
from six.moves import urllib
from visdom_wrapper import VizWrapper
from visdom import Visdom

time.sleep(1)
# Change server port

if _platform == "linux" or _platform == "linux2":

# MAC OS X
elif _platform == "darwin":
videofile = '/Users/%s/trailer.ogv' % getpass.getuser()
# download video
urllib.request.urlretrieve(video_url, videofile)
if os.path.isfile(videofile):
with VizWrapper("vedio_1") as viz_wrapper:
viz_wrapper.update_wins(

使用visdom包装器，可以更方便地使用visdom。
- 您不必显式地创建visdom对象。
- 您不必显式管理visdom窗口。用 相同的名称将隐式更新到同一visdom窗口。
- 所有visdomapi仍然可用，您仍然可以在 灵活的方式。
