[PYTHON] I want to use a virtual environment with jupyter notebook!

Background

It turned out that a code error occurs in the latest version of TensorFlow when I try to proceed with learning with "Deep Learning starting with TensorFlow" (Impress Takuya Niimura = author). Considering that the same situation will occur in the future, I wanted to master the construction of a virtual environment, so I created an environment. This article is a memorandum.

Purpose

-Create a virtual environment and install TensorFlow 1.4 -Use the created virtual environment with jupyter notebook

procedure

Install the library that will add the kernel to your base environment.

pip install environment_kernels

Next, create a new virtual environment. I also installed python, jupyter, and ipykernel.

conda create -n hoge python=3.6 jupyter ipykernel
conda info -e
$base ＊ C:/Users/...　 #Active environment
$hoge    C:/Users/...

Activate the virtual environment you created.

activate hoge
$(hoge) C:\Users\...>  #Is displayed, OK

Create a config file for jupyter notebook.

jupyter notebook --generate-config

.jupyter / jupyter_notebook_config.py will be created, so add the following to an appropriate location.

c.NotebookApp.kernel_spec_manager_class = 'environment_kernels.EnvironmentKernelSpecManager'
c.EnvironmentKernelSpecManager.conda_env_dirs=['/home/User/Anaconda3/envs/']

In [], specify the folder where the virtual environment is saved.

Set the virtual environment in the kernel.

ipython kernel install --user --name=hoge

For the time being, the virtual environment can be used in this state. Launch jupyter notebook and it should be added to the kernel tab. After that, please like it as it is boiled or baked.
