PyTorch Tensorboard 中的投影仪选项卡为空白

Question

我正在尝试可视化每个时期的嵌入。但是投影仪页面显示了这一点 -

这是页面上的文字 -

No checkpoint was found.

Probable causes:

    No checkpoint has been saved yet. Please refresh the page periodically.
    You are not saving any checkpoint. To save your model, create a tf.train.Saver and save your model periodically by calling saver.save(session, LOG_DIR/model.ckpt, step).

If you’re new to using TensorBoard, and want to find out how to add data and set up your event files, check out the README and perhaps the TensorBoard tutorial.

If you think TensorBoard is configured properly, please see the section of the README devoted to missing data problems and consider filing an issue on GitHub.

为了简化事情，我使用以下内容在我的训练循环中生成嵌入；还是不行。

for e in epochs:
    .
    .
    writer.add_embedding(torch.randn(100, 5), global_step=e)

我在这里错过了什么？

Answer 1

遇到同样的错误后，我尝试运行嵌入的示例脚本，但它突然起作用了。

我将其缩小为：在添加嵌入之前或之后将任何图像添加到 Tensorboard 使其工作。像这样：

writer.add_image('image', np.ones((3,3,3)), 0)

不确定是什么原因造成的。
