参考 https://github.com/lanpa/tensorboardX
支持scalar, image, figure, histogram, audio, text, graph, onnx_graph, embedding, pr_curve and video summaries.
例子要求tensorboardX>=1.2 and pytorch>=0.4
安装
pip install tensorboardX 或 pip install git+https://github.com/lanpa/tensorboardX

运行: python demo.py 会出现runs文件夹，然后在cd到工程目录运行tensorboard --logdir runs

安装和启动
安装： pip install visdom
启动：python -m visdom.server示例
from visdom import Visdom
#单张
viz.image(
np.random.rand(3, 512, 256),
opts=dict(title=\\\\\'Random!\\\\\', caption=\\\\\'How random.\\\\\'),
)
#多张
viz.images(
np.random.randn(20, 3, 64, 64),
opts=dict(title=\\\\\'Random images\\\\\', caption=\\\\\'How random.\\\\\')
)
from visdom import Visdom
image = np.zeros((100,100))
vis = Visdom()
vis.text("hello world!!!")
vis.image(image)
vis.line(Y = np.column_stack((np.random.randn(10),np.random.randn(10))),
X = np.column_stack((np.arange(10),np.arange(10))),
opts = dict(title = "line", legend=["Test","Test1"]))
