Note: on June 1st 2017, we used the following step in order to downgrade conda and be ready to install UV-CDAT 2.10 that required an older version of conda (strictly older than 4.3.13) than the one used for 2.8

bash-4.1$ conda install -n root "conda<4.3.13"

Package plan for installation in environment /home/share/unix_files/cdat/miniconda2:

The following packages will be DOWNGRADED due to dependency conflicts:

    conda: 4.3.13-py27_0 --> 4.3.11-py27_0

Proceed ([y]/n)? y

You should download the test 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…)

(cdatm14) bash-4.1$ python -c 'import vcs; vcs.download_sample_data_files(); print "\nFinished downloading sample data to", vcs.sample_data'

After cloning, we are ready to install some extra packages that may be requested by LSCE users

Lists of installed packages: lsce-extra_01_install_160223.txt

The following packages have no dependency problems and were installed later

• High resolution data for basemap
  • conda install -n cdatm14 -c conda-forge basemap-data-hires
• PCMDI metrics package (PMP)
  • conda install -n cdatm14 -c conda-forge -c pcmdi pcmdi_metrics
• XlsxWriter: a Python module for creating Excel XLSX files
  • conda install -n cdatm14 xlsxwriter
  • Note: this is a dependency of dreqPy
• dreqPy: CMIP6 Data Request Python API
  • pip install dreqPy
  • Update with: pip install --upgrade dreqPy
    • Get version number with:
      

      $ drq -v
      dreqPy version 01.00.06 [Version 01.00.06]

• CMOR: CMOR (Climate Model Output Rewriter) is used to produce CF-compliant netCDF files
  • conda install -n cdatm14 -c conda-forge -c pcmdi -c uvcdat cmor
    • Did not complete the installation yet, because it requested a downgrade of libnetcdf (see github issue)
    • Installation issue was solved in cmor-3.2.3

Add here packages that would be useful but have some problems that prevent their installation

• ESMPy: ESMF Python Regridding Interface
  • conda install -n cdatm14 -c conda-forge esmpy
  • Installation of esmpy 7.0.0 did not report errors, but esmpy seemed to have libraries based importation problems and has been removed
    • conda -n cdatm14 remove esmpy

• shapely request a downgrade of geos when installed from conda-forge (see github issue) but it will work when installed from the default repo
  • conda install -n cdatm14 shapely
  • We get a slightly older version (1.5.16-py27_0 instead of 1.5.17-np111py27_2)
  • Note: cartopy (below) requests the same downgrade of geos…
• cartopy requests a downgrade of geos and matplotlib (see github issue)
  • We install the requested dependencies and then we force the installation of cartopy

• trying to install rpy2 will trigger the installation of R!
  • We force the installation of only rpy2 in order to use the R already installed at LSCE
    • conda install --force -n cdatm14 -c conda-forge -c uvcdat rpy2

• pillow: the friendly PIL (Python Imaging Library) fork
• pandas: Python Data Analysis Library
• statsmodels: a Python module that allows users to explore data, estimate statistical models, and perform statistical tests
• seaborn: statistical data visualization
• scikit-image: image processing in Python
• seawater: Python re-write of the CSIRO seawater toolbox
• gsw: Python implementation of the Thermodynamic Equation Of Seawater
• netcdf4: a Python interface to the netCDF C library
• pyferret: Ferret encapsulated in Python
• vacumm: Validation, Analysis, Comparison - Utilities written in Python to validate and analyze Multi-Model outputs, and compare them to observations
• basemap-data-hires: high resolution data for basemap
• PCMDI metrics package (PMP): objectively compare results from climate models with observations using well-established statistical tests
• XlsxWriter: a Python module for creating Excel XLSX files
• dreqPy: CMIP6 Data Request Python API
• CMOR: CMOR (Climate Model Output Rewriter) is used to produce CF-compliant netCDF files

• shapely: a Python wrapper for GEOS for algebraic manipulation of geometry (manipulation and analysis of geometric objects in the Cartesian plane)
• cartopy: a library providing cartographic tools for python
• rpy2: providing simple and robust access to R from within Python

• wget: pure python download utility
  • Used conda install -n cdatm14 -c daler wget=3.2 in order to get version 3.2, the same as the one on Pypi
  • REMOVED because it did not work correctly in the script where it was needed: it emulated wget with ftp and failed in our case after downloading the first file

After following the steps above, we get the following environments. Use the conda info –envs command to get the up-to-date list of available environments
