====== JYP's Python distribution (2024-03) ====== [ [[.:index|Back to all versions]] ] If you have questions about Python, read: * [[other:python:starting|Working with Python]] * [[other:python:jyp_steps|JYP's recommended steps for learning python]]! ===== Using JYP's distribution ===== If you only need to use this distribution, just use the following steps and then read the [[#what_should_i_do_now|What should I do now?]] section below. There are more details on this page if you want to install a similar distribution yourself * Initialize //conda// with: ^ Server ^ tcsh ^ bash ^ | LSCE | ''source ~jypeter/.conda3_jyp_2024-03.csh'' | ''source ~jypeter/.conda3_jyp_2024-03.sh'' | | spirit[x] | ''source ~jypmce/.conda3_jyp.csh''\\ n/a | ''source ~jypmce/.conda3_jyp.sh''\\ n/a | * Choose one of the [[#environments_summary|installed environments]] and activate it with: ''conda activate env_name'' * python 2.7.x: Deprecated! If you still need to use python 2.7, please use [[other:uvcdat:cdat_conda:cdat_8_1|CDAT 8.1]] * python 3.x: ''conda activate cdatm_py3'' * Type ''which python'' (or the ''wp'' alias) and make sure you get something looking like * ''[...]/miniconda3/envs//bin/python'' * e.g. ''cdatm_py3'' environment at LSCE:\\ ''/home/share/unix_files/cdat/miniconda3_21-02/envs/cdatm_py3/bin/python'' ===== What should I do now? ===== ==== You just want to use the installed distribution ==== You are ready if you have typed the ''conda activate'' command specified in the previous section! * You may want to add the ''source'' line to your shell configuration file so that you don't have to remember it and type it each time you open a new terminal * Note: it's better to type the ''activate'' command in a terminal only when you want to use this specific version of python, rather than having the ''activate'' in your shell configuration file. This may have some side effects in some cases * Have a look at the [[other:uvcdat:cdat_conda:cdat_8_1#extra_packages_list|Extra package list]] at the bottom of this page to see what is available in this distribution * If you have not done it yet, read (or at least have a look at the list of sections): * [[other:python:starting|Working with Python]] * [[other:python:jyp_steps|JYP's recommended steps for learning python]] ==== You want to replicate this distribution on your own server or a desktop/laptop ==== Read the next sections of this web page There are some slight differences depending on how and where you want to install this distribution: * **Only for you**\\ This is the common case. Well, if you break something you can always remove everything and start from scratch * For **sharing a stable version with several other people**\\ You should be careful not to break a shared installation! * Be extremely careful with packages that require downgrading other packages/dependencies (especially downgrading key packages like ''numpy'' and ''matplotlib''). * Try to avoid packages only based on ''pip'' The notes at the beginning of each section will tell you if you can skip the section if you are just installing for you ===== What's New in JYP's 2024-03 distribution? ===== * This is the first distribution not //tied// to CDAT packages * There are lots (and lots) of extra packages that all have their own history. You can always visit the [[#extra_packages_list|Extra package list]] on this page, to get news from individual packages ===== Installation with Miniconda3 ===== ==== Installing Miniconda3 ==== If //Miniconda3// is not already installed, or if you want to start over with a brand new (or clean) version of //Miniconda3//, read [[other:uvcdat:cdat_conda:miniconda3_install|JYP steps for installing Miniconda3]]. ==== Installing CDAT 8.2.1 ==== === Prerequisites === We first check that we have indeed access to a //(mini)conda// installation (the //base// environment we get if we have correctly installed miniconda3), and we assume that we have a write-access to the conda disk hierarchy, and a few Gb of disk space available > conda env list | grep base base * /home/share/unix_files/cdat/miniconda3_21-02 > df -h /home/share/ Filesystem Size Used Avail Use% Mounted on prolix3:/share 917G 245G 626G 29% /home/share > du -sh /home/share/unix_files/cdat/miniconda3_21-02 577M /home/share/unix_files/cdat/miniconda3_21-02 We can also use ''conda env list'' and remove some obsolete versions with ''conda remove -n obsolete_environment %%--%%all'', in order to free up some space === Python 2.7 version === Python 2.x is deprecated in CDAT, starting with CDAT 8.2.1. If you still need to use python 2.7, please use [[other:uvcdat:cdat_conda:cdat_8_1|CDAT 8.1]] === Python 3.8 version === It's possible that, when using the //tcsh// shell and trying to use the ''conda create -n cdat-8.2.1_py3 lots_of_parameters_with_wildcards'' line, you will get the following error message: **conda: No match** Apparently the //tcsh// version of conda does not like wildcards too much ([[https://gitmemory.com/issue/conda/conda/9771/608209654|CSH install/search fail with '*' variable in an argument]])... In that case, just type ''bash'' and run the installation command in a //bash// shell The installation line below is based on information from the [[https://github.com/CDAT/cdat/wiki/install#for-linux-python|CDAT wiki page]].

The initial CDAT environment is strictly the one created at PCMDI and certified by PCMDI. Rather than making changes directly in there, we keep it as it is, clone it, and make changes in the cloned environment * Carefully working on different python environments (possibly cloned) is safer in a multi-user environment (i.e. you can have people use a specific environment, and make tests in another environment) * Cloning a full environment uses Linux hard links and requires less disk space than making a real copy $ conda create -n cdatm19_py3 --clone cdat-8.2.1_py3 $ cd /home/share/unix_files/cdat/miniconda3_21-02/envs $ du -sh cdat-8.2.1_py3 cdatm19_py3 2.5G cdat-8.2.1_py3 538M cdatm19_py3 ===== Getting ready for a moving default CDAT environment ===== You can skip this section if you are **installing CDAT just for one user (yourself)** on a Linux machine (or a Windows 10 machine with WSL) You will directly make changes and install packages in **your** main python environment This step could probably be listed at the **end**, especially in a multi-user environment! If there is already a ''cdatm_py3'' link (pointing to an older environment), make sure that the new CDAT environment is stable and working correctly before updating the ''cdatm_py3'' link We create a **//cdatm_py3// symbolic link** in the ''envs'' directory, that has a //stable name// but can be moved to point to the latest default (and hopefully stable) CDAT environment. In that case, most users can just activate this //cdatm_py3// environment and always get the latest stable version. $ cd /home/share/unix_files/cdat/miniconda3_21-02/envs $ ln -s cdatm19_py3 cdatm_py3 conda env list # conda environments: # base * /home/share/unix_files/cdat/miniconda3_21-02 cdat-8.2.1_py3 /home/share/unix_files/cdat/miniconda3_21-02/envs/cdat-8.2.1_py3 cdatm19_py3 /home/share/unix_files/cdat/miniconda3_21-02/envs/cdatm19_py3 cdatm_py3 /home/share/unix_files/cdat/miniconda3_21-02/envs/cdatm_py3 $ ls -l /home/share/unix_files/cdat/miniconda3_21-02/envs/ drwxr-xr-x [...] cdat-8.2.1_py3/ drwxr-xr-x [...] cdatm19_py3/ lrwxrwxrwx [...] cdatm_py3 -> cdatm19_py3/ ===== Customizing CDAT for LSCE ===== ==== A quick test of cdms2 and vcs ==== You can use the quick test shown in [[https://github.com/CDAT/cdat/wiki/install#to-test-your-cdat-installation|To Test Your CDAT Installation]], and check if you get the expected png file You can also check the [[other:uvcdat:cdat_conda:cdat_8_1#testing_vcs|Testing vcs]] section of the LSCE installation of CDAT 8.1 ==== Downloading cdms2/vcs test data ==== You should download the test data (174M of data...) and use it in the example scripts that you want to distribute, and scripts you write for reporting the errors you find (if any...). The downloaded data files will be available in: ''vcs.sample_data'' $ conda activate cdatm19_py3 (cdatm19_py3) $ python -c 'import vcs; vcs.download_sample_data_files(); print("\nFinished downloading sample data to " + vcs.sample_data)' [...] Finished downloading sample data to /home/share/unix_files/cdat/miniconda3_21-02/envs/cdatm19_py3/share/cdat/sample_data (cdatm19_py3) $ du -sh /home/share/unix_files/cdat/miniconda3_21-02/envs/cdatm19_py3/share/cdat/sample_data 174M /home/share/unix_files/cdat/miniconda3_21-02/envs/cdatm19_py3/share/cdat/sample_data $ python >>> import os, vcs >>> vcs.sample_data '/home/jypeter/miniconda3_21-02/envs/cdat-8.2.1_py3/share/cdat/sample_data' >>> os.listdir(vcs.sample_data) ['BlueMarble.ppm', 'clt.nc', 'geo.1deg.ctl', 'geo.1deg.gmp', 'geo.1deg.grb', ...] ==== Packages that have no dependency problems ==== After [[#cloning_the_base_cdat_environment_before_adding_specific_packages_for_lsce|cloning]], we are ready to install some extra (e.g. not directly related to CDAT) packages that may be useful to LSCE users * We first install together as many packages as possible that don't require other channels than //conda-forge//, and that don't request a significant downgrade of what is already installed * We use the //dry-run// option of conda in order to check the version (theoretically the latest) and origin (theoretically //conda-forge//) of the packages that would be installed. Or maybe the result will be that there are too many conflicts and the installation cannot proceed with the requested packages combination * conda may take a very long time to report that there are too many conflicts and we have started using [[https://github.com/mamba-org/mamba|mamba]] that uses different solving libraries and is much (**much!**) faster than conda * if the dry-run reports too many conflicts or requests too many downgrades, we try to remove some (not really important) packages and check if it works better * the last resort is too create a new environment with a smaller set of packages if a user really needs a conflicting package * We later install individual extra packages with ''conda install'', ''mamba install'' or ''pip install'' === Pre-installation check with the dry-run option === /usr/bin/time mamba install -n cdatm19_nompi_py3 --dry-run -c conda-forge basemap basemap-data basemap-data-hires cartopy cmocean cmor ferret_datasets gdal gdal geopandas glances gsw iris joblib netcdf4 palettable pandas pillow pyferret rpy2 scikit-image scikit-learn seaborn seawater shapely spyder statsmodels windspharm wrf-python xarray xlsxwriter [... lots of information about what would be done followed by some information about how long it took ...] Summary: Install: 167 packages Downgrade: 3 packages Total download: 474 MB DryRunExit: Dry run.
