The Anaconda Python distribution is system software.
Otherwise, keep reading to learn how to install packages into custom environments (not the base environment). If the packages you need are on the list or are found in the Python standard library then you can begin your work. There are hundreds of packages pre-installed and ready to be used with a simple import statement. # packages in environment at /usr/licensed/anaconda3/2021.11: To see all the pre-installed Anaconda packages and their versions use the conda list command: One cannot make any changes to base environment. The command prompt is preceeded by "(base)" which indicates that conda is operating on the base environment. In fact, the new python and python3 commands are identical as they are in fact symbolic links to python3.9. We now have an updated version of Python and related tools. Let's inspect our newly loaded Python by using the same commands as above: To make Anaconda Python available, run the following command: In fact, many of these packages are optimized for our hardware. In addition to Python's vast built-in library, Anaconda provides hundreds of additional packages which are ideal for scientific computing.
On the Princeton HPC clusters we offer the Anaconda Python distribution as replacement to the system Python. We see that both python2 and python3 are installed in a system directory. To learn about the system Python, run these commands: When you first log in to one of the clusters, the system Python is available but this is almost always not what you want. Watch a PICSciE workshop video about Conda environments and Python. See step-by-step directions for uploading files and running a Python script. Python 2 has been unsupported since January 1, 2020. There are no anaconda modules for Python 2 on the other clusters. On Tiger, if for some reason you are trying to install a Python 2 package then use module load anaconda/ instead of anaconda3/ in the directions above. If the installation was successful then your job can be submitted to the cluster with: #SBATCH -mail-type=end # send email when job ends #SBATCH -mail-type=begin # send email when job begins #SBATCH -time=00:01:00 # total run time limit (HH:MM:SS) #SBATCH -mem-per-cpu=4G # memory per cpu-core (4G per cpu-core is default) #SBATCH -cpus-per-task=1 # cpu-cores per task (>1 if multi-threaded tasks) #SBATCH -ntasks=1 # total number of tasks across all nodes #SBATCH -job-name=py-job # create a short name for your job On the command line, use conda deactivate to leave the active environment and return to the base environment.īelow is a sample Slurm script (job.slurm): Consider replacing myenv with an environment name that is specific to your work. $ conda create -name ml-env scikit-learn pandas matplotlib -channel conda-forgeĮach package and its dependencies will be installed locally in ~/.conda. Try the following procedure to install your package(s): Commands preceded by the $ character are to be run on the command line. Angular brackets denote command line options that you should replace with a value specific to your work.

If you want to change the version of Python to the latest version, you can do so by utilizing conda update command. Use the conda update Command on the Anaconda Command Prompt You can also issue the command in the following way. Post that, you need to activate the environment using the command below. If you’d like to install the new version of Python in a particular environment, you could use the conda create command. Use the conda create Command on the Anaconda Command Prompt You will find the older versions of Python here. You will find the newer versions of Python here. Use the latest Anaconda installer to update the Python version.
