【问题描述】：
目标使用来自 TensorFlow 的预训练模型example project，更具体地说是Tensorflow hub
1.
- 为此，我尝试使用以下命令安装
tensorflow_hub：conda install -c conda-forge tensorflow-hub -
conda list输出：.... tensorflow-hub 0.12.0 pyhca92ed8_0 conda-forge .... - 到 sagemenaker EC2 实例的 anaconda 环境。
- 整个安装过程运行顺利，没有任何错误，但是当我尝试导入包时，它就像没有安装一样
import tensorflow_hub as hub - 错误
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-14-5c017171c13e> in <module>
----> 1 import tensorflow_hub as hub
ModuleNotFoundError: No module named 'tensorflow_hub'
- 我已经手动下载了模型并上传到了ec2，但是不知道怎么加载和使用
- 使用 pip 添加 tensorflow_hub https://stackoverflow.com/a/43729857/10270590
1. Run `conda create -n venv_name` and `source activate venv_name`, where `venv_name` is the name of your virtual environment.
2. Run `conda install pip`. This will install pip to your venv directory.
3. Find your anaconda directory, and find the actual venv folder. It should be somewhere like `/anaconda/envs/venv_name/`.
4. Install new packages by doing `/anaconda/envs/venv_name/bin/pip install package_name`.
输出
(tf2p37) ubuntu@ip:~/anaconda3/envs/tf2p37/bin$ pip install --upgrade tensorflow-hub
Requirement already satisfied: tensorflow-hub in /home/ubuntu/anaconda3/envs/tf2p37/lib/python3.7/site-packages (0.12.0)
Requirement already satisfied: protobuf>=3.8.0 in /home/ubuntu/anaconda3/envs/tf2p37/lib/python3.7/site-packages (from tensorflow-hub) (3.15.2)
Requirement already satisfied: numpy>=1.12.0 in /home/ubuntu/anaconda3/envs/tf2p37/lib/python3.7/site-packages (from tensorflow-hub) (1.19.5)
Requirement already satisfied: six>=1.9 in /home/ubuntu/anaconda3/envs/tf2p37/lib/python3.7/site-packages (from protobuf>=3.8.0->tensorflow-hub) (1.15.0)
- 它就在那里，但是当我执行时它仍然不想被导入：
import tensorflow_hub as hub
【问题讨论】：
-
1) 请使用以下命令在 sagemaker（新创建的内核）中打开新笔记本后，尝试在新的 anaconda 虚拟环境中安装（然后导入）最新版本的 tensorflow2.x 和 tensorflow-hub :- a)!pip install --upgrade tensorflow b)!pip install --upgrade tensorflow_hub c)import tensorflow as tf d)import tensorflow_hub as hub 2)通过hub加载模型，请使用： hub_model = hub.load( 'tfhub.dev/google/magenta/arbitrary-image-stylization-v1-256/…)
