如何在 Kaggle 上安装最新版本的 tensorflow？

Question

我想在 Kaggle 上使用特定版本的 Tensorflow。

# This Python 3 environment comes with many helpful analytics libraries installed
# It is defined by the kaggle/python docker image: https://github.com/kaggle/docker-python
# For example, here's several helpful packages to load in 
!pip uninstall tensorflow -y
!pip install -q tensorflow-datasets tf-nightly==2.2.0-dev20200319
import tensorflow as tf
import tensorflow_datasets as tfds
import os
# Input data files are available in the "../input/" directory.
# For example, running this (by clicking run or pressing Shift+Enter) will list all files under the input directory

print(tf.__version__)

Kaggle 上的输出是：

2.1.0

所以它没有选择我尝试安装的版本。

如何在 kaggle 上使用 2.2.X 版本以上？

Answer 1

在关于 TPU 使用的 Kaggle 文档中，他们指定 TensorFlow 2.1 支持 TPU，所以我想知道它是否可能。 您不必卸载 TensorFlow，老实说，我不确定卸载是否会有所作为。

这是我在 Kaggle 笔记本中尝试的内容：

!pip install tensorflow==2.2给出了这个错误：

!pip install tensorflow==1.1给出了同样的错误

但是， !pip install tensorflow和!pip install tensorflow==2.1可以工作，但是它安装的是 TensorFlow 2.1。

查看https://www.kaggle.com/docs/tpu了解更多信息，或者也可以给他们发电子邮件询问。 如果他们只将 TF 2.1 用于他们的内核，那将是有道理的。
