导入 tensorflow_datasets 时出现错误 [英] I get an error when importing tensorflow_datasets

问题描述

我想在 Jupyter(版本 6.0.0)中使用 Python3 tensorflow_datasets.这样做会导致出现错误消息，我似乎无法理解问题是什么.

I want to use in Jupyter (version 6.0.0) with Python3 tensorflow_datasets. Doing that results in an error message I cannot seem to fathom what the problem is.

我为 Python 制作了一个新内核，它应该使用 tensorflow_datasets.采取了以下步骤(在 anaconda 中使用我的管理员选项).

I made a new kernel for Python which should utilize the tensorflow_datasets. The following steps were taken (In anaconda using my administrator option).

1. conda info --envs
2. conda create --name py3-TF2.0 python=3
3. conda activate py3-TF2.0
4. pip install matplotlib
5. pip install tensorflow==2.0.0-alpha0
6. pip install ipykernel
7. conda install nb_conda_kernels
8. pip install tensorflow-datasets

关闭后我重新启动了我的笔记本电脑.

Upon closing I restarted my laptop.

当我打开 Jupyter notebook 并将内核更改为 py3-TF2.0 时(请注意，我只能在 ANACONDA NAVIGATOR 中更改内核，而不能在 Jupyter notebook 环境中更改).打开该内核中的脚本，然后按重新启动内核并运行所有脚本"，我收到错误消息.

When I open Jupyter notebook, and change my kernel to py3-TF2.0 (Do note that I only can change my kernel in the ANACONDA NAVIGATOR and NOT in Jupyter notebook enviroment). Open the script within that kernel and press 'restart kernel and run all scripts' I get the error message.

我再次尝试安装内核；它没有错误消息(删除原始内核并替换它似乎不是问题).

I retried installing the kernel again; which has no error messages (Removing the original kernel and replacing it doesnt seem to be a problem).

import numpy as np
import tensorflow as tf
import tensorflow_datasets as tfds

我希望没有错误信息；从而在 Jupyter 中正确导入了我的 tensorflow_datasets.

I expect no error message; and thus imported my tensorflow_datasets properly in Jupyter.

我得到的错误信息如下

我已经在 Stackoverflow、google 和 youtube 上搜索过这个问题.到目前为止，我在 stackoverflow 上发现了一个相当相似的案例:不是能够在 jupyter notebook 中导入 tensorflow_datasets 模块，但错误消息似乎与我的完全不同.

I have searched on Stackoverflow, google and youtube on this matter. So far I found a rather similar case on stackoverflow : Not able to import tensorflow_datasets module in jupyter notebook but the error message seem to be entirely different from mine.

推荐答案

我找到了答案；问题在于 Tensorflow2.0.0-alpha0这是用 Tensorflow2.0.0 的测试版修补的

I have found the answer; the problem lies within Tensorflow2.0.0-alpha0 This is patched with the beta version of Tensorflow2.0.0
