Create your own deep learning environment with CONDA

The training of deep learning , Reasoning , Testing is inseparable python Language , We usually use conda Tools to build an environment , After installation conda in the future , By default, the corresponding version of pip And python,conda The higher the version , Corresponding python And pip The higher the version .

The environment create

After installation, use the command conda activate Activate conda Built in environment , namely base Environmental Science , This is installing conda Environment created automatically when . If you want to create other environments , Then use the following command to create ：

# Create a your_env_name Environment 
conda create --name your_env_name
# or 
conda create --n your_env_name
# Create specific python Version environment 
conda create --name your_env_name python=2.7
conda create --name your_env_name python=3.6

To delete an environment

conda remove -n your_env_name --all
# or 
conda remove --name your_env_name --all

View the created environment

matters needing attention

Note that you are creating conda It is best to specify the environment used python edition , Not in one conda Install multiple in the environment python, Otherwise, it is easy to get confused . After creating your own environment , Input python View the environment you created python Is the version correct , You can type python or python3, Check whether the version used is consistent , occasionally python The default is python2.7 Version, not python3.X edition , If the versions are inconsistent , Then you must pay attention to using when installing related libraries Python2 still python3. Because to use pip Install related libraries , At this time, you can enter pip See which one corresponds python edition , Here's the picture ,pip and pip3 The corresponding python Version inconsistency , Then you should pay attention when installing , To use pip still pip3. Under normal circumstances, you create conda The default environment is to use pip Of , instead of pip3, namely ： Suppose you specify the python edition , So use pip -V see pip You can see the used python The version is and specified python edition .

attach ：pip Install and uninstall

sudo apt install pip-python # Use later pip Installation Library 
sudo apt install pip-python3 # Use later pip3 Installation Library 


sudo apt remove pip-python # Delete pip
sudo apt remove pip-python3 # Delete pip3
