Conda basics Verify conda is installed, check version number Update conda to the current version Install a package included in Anaconda Run a package after install, example Spyder* Update any installed program Command line help
*Must be installed and have a deployable command, usually PACKAGENAME
conda create --name py35 python=3. WINDOWS: activate py LINUX, macOS: source activate py conda env list
conda create --clone py35 --name py35- conda list conda list --revisions conda install --revision 2 conda list --explicit > bio-env.txt conda env remove --name bio-env WINDOWS: deactivate macOS, LINUX: source deactivate conda env create --file bio-env.txt conda create --name bio-env biopython
Use conda to search for a package See list of all packages in Anaconda
conda search PACKAGENAME https://docs.anaconda.com/anaconda/packages/pkg-docs
Finding conda packages
Using environments Create a new environment named py35, install Python 3. Activate the new environment to use it
Get a list of all my environments, active environment is shown with * Make exact copy of an environment List all packages and versions installed in active environment List the history of each change to the current environment Restore environment to a previous revision Save environment to a text file Delete an environment and everything in it Deactivate the current environment
Create environment from a text file Stack commands: create a new environment, name it bio-env and install the biopython package
conda create --name py34 python=3.
Windows: activate py Linux, macOS: source activate py Windows: where python Linux, macOS: which -a python
python --version
Installing and updating packages Install a new package (Jupyter Notebook) in the active environment Run an installed package (Jupyter Notebook) Install a new package (toolz) in a different environment (bio-env) Update a package in the current environment Install a package (boltons) from a specific channel (conda-forge) Install a package directly from PyPI into the current active environment using pip Remove one or more packages (toolz, boltons) from a specific environment (bio-env)
Specifying version numbers Ways to specify a package version number for use with conda create or conda install commands, and in meta.yaml files. Constraint type Specification Result Fuzzy numpy=1.11^ 1.11.0, 1.11.1, 1.11.2, 1.11.18 etc. Exact numpy==1.11^ 1.11. Greater than or equal to "numpy>=1.11"^ 1.11.0 or higher OR "numpy=1.11.1|1.11.3"^ 1.11.1, 1.11. AND "numpy>=1.8,<2"^ 1.8, 1.9, not 2. NOTE: Quotation marks must be used when your specification contains a space or any of these characters: > < | *
