Use of Anaconda in Ubuntu
New Anaconda environment on Ubuntu###
- 1. Anaconda environment
- 2. Create a new environment
- 3. Installation dependencies
- 4. Pycharm Development Tools
- 5. Enter and exit the base environment
1. Anaconda environment#
The ubuntu system has python2 and python3 environments by default, but we do not use the system environment.
As a programmer, I don't know how many projects will be developed in the future, nor how complicated the environment will be in the future.
There is only such a set of system default environment. If there are more projects in the future, each project will load its own software dependencies into the default environment, which may cause system dependencies problems.
Our normal practice is that each project has its own unique set of environment, which will not conflict with other project environments and will not interfere with each other.
Anaconda is used to solve this environmental problem.
2. Create a new environment#
Open a command line terminal:
conda create -n environment name python=x.x.x
conda create -n environment namemeans to create a new environment
python=xxxmeans that in this environment, install pythonx.xx version
Will always prompt whether to install or not, just enter Y
3. Installation dependencies#
After the installation is complete, if you need to install dependencies, enter on the command line:
conda activate environment name
conda activate environment namemeans to enter the newly established independent environment
After entering the pyqt environment, enter on the command line:
conda install dependency name
conda install pyqtmeans to install dependencies in the current environment.
It will always prompt whether to install or not, just enter Y.
4. Pycharm development tools#
- Set project name
- Choose an existing environment
- Enter environment selection
- Choose conda environment
- Click environment selection
- Choose
pyqtenvironment - The address is
/home/itcast/anaconda3/envs/pyqt/bin/python
- confirm
5. Enter and exit the base environment#
Enter the conda base environment
conda activate base
Exit the conda base environment
conda deactivate
If you cancel the base environment that automatically activates conda every time you start it, you can achieve it by setting the auto_activate_base parameter to false:
conda config --set auto_activate_base false
Edit conda environment variables
nano ~/.bashrc
