如何在 pytorch 中使用张量板？

Question

我正在关注 pytorch tensorboard 教程：https ://pytorch.org/tutorials/intermediate/tensorboard_tutorial.html 。

但由于以下错误，我什至无法启动：

from torch.utils.tensorboard import SummaryWriter

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
~/apps/anaconda3/envs/torch/lib/python3.7/site-packages/torch/utils/tensorboard/__init__.py in <module>
      1 try:
----> 2     from tensorboard.summary.writer.record_writer import RecordWriter  # noqa F401
      3 except ImportError:

ModuleNotFoundError: No module named 'tensorboard'

During handling of the above exception, another exception occurred:

ImportError                               Traceback (most recent call last)
<ipython-input-4-c8ffdef1cfab> in <module>
----> 1 from torch.utils.tensorboard import SummaryWriter
      2 
      3 # default `log_dir` is "runs" - we'll be more specific here
      4 writer = SummaryWriter('runs/fashion_mnist_experiment_1')

~/apps/anaconda3/envs/torch/lib/python3.7/site-packages/torch/utils/tensorboard/__init__.py in <module>
      2     from tensorboard.summary.writer.record_writer import RecordWriter  # noqa F401
      3 except ImportError:
----> 4     raise ImportError('TensorBoard logging requires TensorBoard with Python summary writer installed. '
      5                       'This should be available in 1.14 or above.')
      6 from .writer import FileWriter, SummaryWriter  # noqa F401

ImportError: TensorBoard logging requires TensorBoard with Python summary writer installed. This should be available in 1.14 or above.

我通过 conda 安装了 pytorch 1.14。我应该安装其他东西吗？

Answer 1

该教程可能会让您知道您需要安装 tensorboard。查看pytorch tensorboard 文档，其中解释了您需要先安装 tensorboard。

基本上你可以使用安装张量板

pip install tensorboard

然后通过运行启动张量板服务器

tensorboard --logdir=runs

该runs目录是您的摘要编写器将写入的位置，也是 tensorboard 服务器读取以了解要可视化的内容的位置。
