<p>最近因为工作需要，看了下tensorboard的使用方式，这里做了简单的学习记录。使用的tensorflow版本是<strong>1.10.0</strong>,tensorboard的版本也是一样。</p>
<h1 id="tensorboard介绍"><a href="#tensorboard介绍" class="headerlink" title="tensorboard介绍"></a>tensorboard介绍</h1><p>tensorboard主要是为了查看tensorflow程序，将程序进行图示化，可以用来查看程序的运行情况，也可以用来debug程序。</p>
<h2 id="tensorflow写tensorboard日志"><a href="#tensorflow写tensorboard日志" class="headerlink" title="tensorflow写tensorboard日志"></a>tensorflow写tensorboard日志</h2><p>在程序中主要使用<code>tf.summary.FileWriter</code>来将需要记录的事件日志记录到硬盘中。这个函数主要由三个参数需要注意的，如果想要查看详细的内容，可以去源码中查找具体的使用方式。</p>
<figure class="highlight yaml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="string">logdir:指定日志写入的具体目录</span></span><br><span class="line"><span class="string">graph:指定记录的tensorflow图</span></span><br><span class="line"><span class="string">filename_suffix:事件日志文件的后缀</span></span><br></pre></td></tr></table></figure>
<h2 id="tensorboard启动"><a href="#tensorboard启动" class="headerlink" title="tensorboard启动"></a>tensorboard启动</h2><p>tensorboard的启动是在命令行中，输入<code>tensorboard --logdir=/path/to/log</code>命令启动，然后打开ip+port在浏览器中进行查看。查看tensorboard的参数信息，可以运行<code>tensorboard --help</code>来进行查看。</p>
<figure class="highlight yaml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line"><span class="string">--inspect:</span> <span class="string">用来查看事件日志信息，并不启动tensorboard</span></span><br><span class="line"><span class="string">--logdir：用来指定事件日志的存储目录</span></span><br></pre></td></tr></table></figure>
<p>tensorboard主要是扫描logdir指定目录下的内容，扫描文件名带有<em>.tfevents.</em>的文件进行展示。如果logdir下有多个目录，则在浏览器中可以分别进行浏览。如果有多个相同的文件，则会显示时间戳距离最近的文件。文件名中带有时间戳。例如：<strong>events.out.tfevents.1545795299.DESKTOP-123</strong></p>
