python-3.x - 如何修复当我尝试在终端上运行构建图时弹出的张量板错误

Question

我试图使用张量板查看我的线性回归代码图，但它给出了许多我找不到解决方法的错误。此外，我还在配备 intel m5 cpu 和 intel HD 5300 gpu 的 MacBook 上运行代码。

该程序运行良好，因此我重新检查了创建和存储图形部分中的任何拼写错误的代码。我什至重新安装了tensorflow(1.12.2)，但弹出了同样的错误。我还可以看到运行代码后立即创建的目录(存储图表的“logdir”)。

import tensorflow as tf

W = tf.Variable([.3], tf.float32)
b = tf.Variable([-.3], tf.float32)

x = tf.placeholder(tf.float32)
y = tf.placeholder(tf.float32)

lm = x * W + b

squared_delta = tf.square(lm - y)
cost = tf.reduce_sum(squared_delta)

optimize = tf.train.GradientDescentOptimizer(0.01)

train = optimize.minimize(cost)

init = tf.global_variables_initializer()

with tf.Session() as sess:
    sess.run(init)

    fw = tf.summary.FileWriter('./event_logs', sess.graph)

    for i in range(100):
        sess.run(train, {x: [1, 2, 3, 4], y: [0, -1, -2, -3]})
        #print(' cost : ', sess.run(cost, {x: [1, 2, 3, 4], y: [0, -1, -2, -3]}))

    print("Variables W and b: {} & {}".format(sess.run(W)[0], sess.run(b)[0]))

    test_data = 3
    print("Value for {} is {}".format(test_data, round((test_data * sess.run(W) + sess.run(b))[0])))

我希望看到一个简单的图表，但是......

Answer 1

运行:

tensorboard --logdir="event_logs/"

这是您存储张量板应加载的文件的位置。看一下代码中的这一行:

fw = tf.summary.FileWriter('./event_logs', sess.graph)

我猜您的项目目录名为 machine_learning，这就是您尝试运行的原因:

tensorboard --logdir="machine_learning/"

但这完全是错误的。
