请移步修改为版本:Pytorch使用TensorboardX进行网络可视化 - 简书
由于在之前的实验中,通过观察发现Loss和Accuracy不稳定,所以想画个Loss曲线出来,通过Google发现可以使用tensorboard进行可视化,所以进行了相关配置。首先安装tensorboardX和tensorflow命令如下:
pip3 install tensorboardX
pip3 install tensorflow (for tensorboard web server)
测试代码:
import torch
import torchvision.utils as vutils
import numpy as npimport torchvision.models as models
from torchvision import datasets
from tensorboardX import SummaryWriter
resnet18 = models.resnet18(False)
writer = SummaryWriter()
sample_rate = 44100
freqs = [262, 294, 330, 349, 392, 440, 440, 440, 440, 440, 440]
for n_iter in range(100):
s1 = torch.rand(1) # value to keep
s2 = torch.rand(1)
writer.add_scalar('data/scalar1', s1[0], n_iter)
writer.add_scalar('data/scalar2', s2[0], n_iter)
writer.add_scalars('data/scalar_group', {"xsinx":n_iter*np.sin(n_iter),
"xcosx":n_iter*np.cos(n_iter),
"arctanx": np.arctan(n_iter)}, n_iter)
x = torch.rand(32, 3, 64, 64)
if n_iter%10==0:
x = vutils.make_grid(x, normalize=True, scale_each=True)
writer.add_image('Image', x, n_iter)
x = torch.zeros(sample_rate*2)
for i in range(x.size(0)):
x[i] = np.cos(freqs[n_iter//10]*np.pi*float(i)/float(sample_rate))
writer.add_audio('myAudio', x, n_iter, sample_rate=sample_rate)
writer.add_text('Text', 'text logged at step:'+str(n_iter), n_iter)
for name, param in resnet18.named_parameters():
writer.add_histogram(name, param.clone().cpu().data.numpy(), n_iter)
writer.add_pr_curve('xoxo', np.random.randint(2, size=100),
np.random.rand(100), n_iter) #needs tensorboard 0.4RC or later
dataset = datasets.MNIST('mnist', train=False, download=True)
images = dataset.test_data[:100].float()
label = dataset.test_labels[:100]
features = images.view(100, 784)
writer.add_embedding(features, metadata=label, label_img=images.unsqueeze(1))
# export scalar data to JSON for external processing
writer.export_scalars_to_json("./all_scalars.json")
writer.close()
最后在工程目录下打开terminal运行
tensorboard --logdir runs
结果为:
