Question

我在Anaconda环境中的macOS系统中使用Python 3.7.3。 Tensorflow（1.14.0），Matplotlib（3.1.0）和其他模块已安装在那里，一切正常。我编写了以下代码并运行它。


import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
def add_layer(inputs, inputs_size, outputs_size,activation_function = None):
    with tf.name_scope('layer'):
        with tf.name_scope('weight'):
            Weights = tf.Variable(tf.random.normal([inputs_size, outputs_size]))        
        with tf.name_scope('biase'):
            biases = tf.Variable(tf.zeros([1,outputs_size])+0.1)
        with tf.name_scope('wx_plus_b'):
            Wx_plus_b = tf.matmul(inputs, Weights) + biases
        if activation_function == None:outputs = Wx_plus_b
        else: outputs = activation_function(Wx_plus_b)
        return outputs

'''
multiple lines omitted here
'''

writer = tf.compat.v1.summary.FileWriter("logs/",sess.graph)

我可以看到一个名称为

的本地文件

"events.out.tfevents.1561289962.Botaos-MacBook-Pro.local"

在“ logs /”文件夹中生成。我打开了终端，并在Anaconda环境激活的情况下将其CD到该文件夹。然后我输入

"python -m tensorboard.main --logdir=‘logs/‘ --host localhost --port 6006"

得到回应

TensorBoard 1.14.0 at http://localhost:6006/ (Press CTRL+C to quit)

然后，无论我使用野生动物园还是Chrome浏览器打开“ http://localhost:6006/”，除了“当前数据集没有活动的仪表板”之外，始终没有显示任何内容。 enter image description here 实际上，我还尝试了其他建议，例如

python -m tensorboard.main --logd logs --host localhost --port 6006

python -m tensorboard.main --logd logs --host localhost --port 6006

但是没有区别。

原始代码如下：

import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
def add_layer(inputs, inputs_size, outputs_size,activation_function = None):
    with tf.name_scope('layer'):
        with tf.name_scope('weight'):
            Weights = tf.Variable(tf.random.normal([inputs_size, outputs_size]))        
        with tf.name_scope('biase'):
            biases = tf.Variable(tf.zeros([1,outputs_size])+0.1)
        with tf.name_scope('wx_plus_b'):
            Wx_plus_b = tf.matmul(inputs, Weights) + biases
        if activation_function == None:outputs = Wx_plus_b
        else: outputs = activation_function(Wx_plus_b)
        return outputs
x_data = np.linspace(-1,1,300,dtype = np.float32)[:,np.newaxis] 
noise = np.random.normal(0,0.05,x_data.shape).astype(np.float32)    
y_data = np.square(x_data) - 0.5 + noise

with tf.name_scope('inputs'):
    xs = tf.compat.v1.placeholder(tf.float32,[None,1],name='x_in')
    ys = tf.compat.v1.placeholder(tf.float32,[None,1],name='y_in')

l1 = add_layer(xs, 1, 10, tf.nn.relu) 

prediction = add_layer(l1, 10, 1, None)

with tf.name_scope('loss'):
    loss = tf.reduce_mean(tf.reduce_sum(tf.square(prediction - ys),reduction_indices=[1])) #no need to do tf.sum() as in link.                  #tf.reduce_mean()
with tf.name_scope('train'):
    train_step = tf.compat.v1.train.GradientDescentOptimizer(0.1).minimize(loss)


sess = tf.compat.v1.Session()

writer = tf.compat.v1.summary.FileWriter("logs/",sess.graph)
sess.run(tf.compat.v1.global_variables_initializer())

我认为问题在于，当您已经在logs目录中时，您正在尝试查找logs目录。

尝试执行：张量板--logdir日志

激活Tensorboard时始终显示“当前数据集没有活动的仪表板”
