Get the list of packages installed in Anaconda

Question

Over a period of time, I have loaded a number of packages into the Anaconda I have been using. Now I am not able to keep track of it. How do we get a list of all packages loaded in Anaconda (Windows 10)? What is the command?

Answer 1

in terminal, type : conda list to obtain the packages installed using conda.

for the packages that pip recognizes, type : pip list

There may be some overlap of these lists as pip may recognize packages installed by conda (but maybe not the other way around, IDK).

There is a useful source here, including how to update or upgrade packages..

To list all of the packages in the active environment, use:

conda list

To list all of the packages in a deactivated environment, use:

conda list -n myenv

To check if a specific package is installed:

conda list html5lib

which outputs something like this if installed:

# packages in environment at C:ProgramDataAnaconda3:
#
# Name                    Version                   Build  Channel
html5lib                  1.0.1                    py37_0

or something like this if not installed:

# packages in environment at C:ProgramDataAnaconda3:
#
# Name                    Version                   Build  Channel

you don’t need to type the exact package name. Partial matches are supported:

conda list html

This outputs all installed packages containing ‘html’:

# packages in environment at C:ProgramDataAnaconda3:
#
# Name                    Version                   Build  Channel
html5lib                  1.0.1                    py37_0
sphinxcontrib-htmlhelp    1.0.2                      py_0
sphinxcontrib-serializinghtml 1.1.3                      py_0

For more conda list usage details:

usage: conda-script.py list [-h][-n ENVIRONMENT | -p PATH][--json] [-v] [-q]
[--show-channel-urls] [-c] [-f] [--explicit][--md5] [-e] [-r] [--no-pip][regex]

Answer 6

To list all of the packages in the active environment in a format that resembles pip freeze:

conda env export

Example of output:

name: pytorch
channels:
  - pytorch
  - anaconda
  - conda-forge
  - defaults
dependencies:
  - python=3.8.5=h7579374_1
  - python_abi=3.8=1_cp38
  - pytorch=1.7.1=py3.8_cuda11.0.221_cudnn8.0.5_0
  - pytorch-lightning=1.1.4=pyhd8ed1ab_0
  - tensorboard=2.4.0=pyhd8ed1ab_0
  - pip:
    - bert-score==0.3.7
    - tokenizers==0.9.4
    - transformers==4.2.1
prefix: /home/franck/anaconda3/envs/pytorch

You can save the environment and re-create and/or reactivate it:

# Save the environment
conda env export > my_conda_env.yml

# Re-create the environment
conda env create --file my_conda_env.yml

# Reactivate the environment
conda activate pytorch

Answer 7

You can see what conda has installed from the history file in your conda environments meta directory. It’s located in $ENV_PATH/conda-meta/history. This will tell you the commands that have run for that environment so should list the explicit specs that you directly installed

https://github.com/conda/conda/issues/8986#issuecomment-572736603

Just have a look for the lines starting with "# cmd:" which further contain "install".
For Windows the path to the history file may start with %env_path% instead of $ENV_PATH.
