张量板错误 - 名称错误：未定义名称'tensorboard'

Question

我现在正在学习TensorFlow，但无法使张板工作。我尝试了下面的简单程序，没有运气。该程序在使用张板代码之前就可以使用，但是当我使用张板代码时，我会收到以下错误：

NameError: name 'tensorboard' is not defined

请任何帮助都可以进行。

import tensorflow as tf

a = tf.constant(5, name="input_a")
b = tf.constant(3, name="input_a")
c = tf.multiply(a,b, name="mul_c")
d = tf.add(a,b, name="add_d")
e = tf.add(c,d, name="add_e")
sess = tf.Session()
sess.run(e)
output = sess.run(e)
writer = tf.summary.FileWriter('/tmp/newtest', graph=sess.graph)
print(sess.run(e))
tensorboard --logdir /tmp/newtest

我相信这已经是'回答了'，但是，为此提供了我所做的示例，我希望它能对您或其他人有所帮助。

这只是涵盖了触发＆amp;显示张板。

import subprocess
import webbrowser
import time
logLocation = 'tflearn_logs'
print("rnWould you like to see the visual results (y/N)? ", end='', flush=True)
answer = input()
if answer.strip().lower() == "y":
    port = str(8018)
    print("Starting Tensorboard to visualize... ")
    process = subprocess.Popen(['tensorboard', "--logdir='" + logLocation + "'", '--port=' + port])
    # Wait for a few seconds, give the tensorboard a headstart
    time.sleep(5)
    print("Opening Tensorboard webpage... ")
    url = 'http://127.0.0.1:' + port + '/'
    # Path differs per OS (Windows, Linux, iOS)
    chrome_path = 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'
    webbrowser.get(chrome_path).open(url) 
print("Press enter to quit... ", end='', flush=True)
answer = input()
if process is not None:
    process.kill()
