无法让 pytorch 与张量板一起工作

Question

我正在通过本教程使用 tensorboard https://pytorch.org/tutorials/intermediate/tensorboard_tutorial.html#设置 pytorch（v1.3.0 通过 conda）

但在台阶上

from torch.utils.tensorboard import SummaryWriter

# default `log_dir` is "runs" - we'll be more specific here
writer = SummaryWriter('runs/fashion_mnist_experiment_1')

我不断收到错误

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)

      3 except ImportError:

ModuleNotFoundError: No module named 'tensorboard.summary'; 'tensorboard' is not a package

During handling of the above exception, another exception occurred:

      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.

有没有人有什么建议？

Answer 1

错误日志说，除其他外，

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

因此，当它尝试导入 TensorBoard 时，它无法这样做，因为它在搜索路径中缺少它。您可以安装最新版本（无需指定任何版本号），如下所示：

$ conda install -c conda-forge tensorboard

除此之外，您可能还需要安装 protobuf：

$ conda install -c conda-forge protobuf

这些安装应该修复ImportErrors。

Answer 2

我遇到了同样的错误，我通过以下步骤解决了：

1. 从 conda 环境中删除了 Tensorflow 或 Tensorboard 的所有安装。
2. 然后通过激活相同的 conda 环境，键入“pip install -U tb-nightly”
3. 然后输入“pip install -U future”
4. 完毕

Answer 3

我认为这是版本问题。

只需运行这个：

pip install tensorboard==1.14.0

（不是 pip install tensorboard==1.14）

或者只安装tensoflow 1.14.0，其中包含tensorboard 1.14.0：

pip install tensorflow==1.14.0

这个版本的张量流在 pytorch 1.2 中为我工作。
