title: ImportError: TensorBoard logging requires TensorBoard version 1.15 or above
body: <p>I follow the tutorials in <a href="https://pytorch.org/tutorials/intermediate/tensorboard_tutorial.html" rel="nofollow noreferrer">pytorch.org</a>
  It occurs error：<code>TensorBoard logging requires TensorBoard version 1.15 or above</code>,but I have install TensorBoard already.
  Here is the code:</p>
  <pre><code>#from torch.utils.tensorboard import SummaryWriter
  from tensorboardX import SummaryWriter
  writer = SummaryWriter('runs/fashion_mnist_experiment_1')
  #get some random training images
  dataiter = iter(trainloader)
  images , labels = dataiter.next()
  #create grid of images
  img_grid = torchvision.utils.make_grid(images)
  matplotlib_imshow(img_grid,one_channel=True)
  writer.add_image('four_fashion_images',img_grid)
  writer.add_graph(net, images)
  writer.close()
  </code></pre>
  <p>Error:</p>

  <p>I use <code>from torch.utils.tensorboard import SummaryWriter</code> at the beginning,but it occurs the error as same as above.Then I use <code>from tensorboardX import SummaryWriter</code></p>
