= Easy Developer Setup Using Anaconda = == Step 1 - Install Anaconda == Download the latest '''64-Bit''' Python '''2.7''' Installer from http://continuum.io/downloads and run it. * The recommended destination folder is as good as any. If you deviate from this then it's probably worthwhile to make sure the path is short and contains no spaces, and is not the same as any previous installation (one reader installed 64 bit on top of previous 32 bit, not a good idea). * At the Advanced Options screen, you need to consider whether or not you want to make Anaconda your default version of Python. Developers who do not work on multiple Python projects can just accept the defaults here. * By default of Windows anaconda is installed for single user and not "everyone", which means you cannot run the conda command from an arbitrary command window. If you proceeded with default installation, you need to open Anaconda Prompt from Menu Start. Otherwise you can install anaconda for everyone, which requires root privlidges. If "conda" is not a recognised command then add the install directory to your Windows user Path variable.[[BR]] * If you have a failing reference to a "conda.binstar.org/!PeterParker/win-64/repodata.json" file, then edit this out of the anaconda start up file at users/username/.condarc as you may still have left it there from an older sasview installation system. == Step 2 - Download !SasView and sasmodels from github == If you don't have git installed, go to the GIT section below ([#anchor1 Step 7]) for instructions, otherwise simply run {{{ git clone https://github.com/SasView/sasview.git sasview git clone https://github.com/SasView/sasmodels.git sasmodels }}} == Step 3 - Install dependencies using yml files == Go to folder: {{{ sasview/build_tools/conda/ymls }}} and create conda enviroment using yml specific for your platform (needs to be run from top-level not within a conda virtual environment) {{{ #Windows conda env create -f sasview-env-build_win.yml #Mac OSX conda env create -f sasview-env-build_osx.yml #Linux conda env create -f sasview-env-build_linux.yml }}} == Step 4 - activate conda enviroment == {{{ #Windows activate sasview else if running from inside a Git Bash shell then use: source activate sasview. #Mac OSX and Linux source activate sasview }}} == Step 5 - run !SasView == You should be ready to run sasview. Go to sasview directory and run {{{ #Windows python run.py #Mac OSX and Linux pythonw run.py To build the documentation you will still first need to do: python setup.py docs }}} == [=#anchor1 Step 6 - try the new qt gui (highly experimental work in progress)] == ''Some notes as of 18 Jan 2018 based on a Windows 7 install. Start with Git bash in your sasview directory.'' source deactivate git checkout ESS_GUI ''Look for sasview/build_tools/conda_py3_qt5_env.yml, open it in an editor, save it somewhere else outside of git control, '''remove''' any pip lines for sasview and sasmodels which will elsewise throw errors. '' conda env create -f=/path to your new yml file/conda_py3_qt5_new.yml source activate qt5 cd src/sas/qtgui python convertUI.py cd ../../.. python run.py ''If run.py gives an error from line 1140 in readCategoryInfo, you likely have the old version of the categories file. Delete the file serial_cat.json from your user directory (C:\\.sasview\ in Windows) and then run the latest *release* version of sasview. This will automatically generate the correct categories.json file.'' ''You may then need to install 64 bit Microsoft Visual C++ 14.0 compiler by following the link requested, as the latest changes to use only TinyCC compiler are not yet merged with this branch. Other useful conda commands:'' conda info --envs ''will show that you now have both sasview and qt5 environments.'' conda env remove --name qt5'' '' ''will remove the qt5 environment, though the files involved seem to stay on your hard drive so a new ''conda env create ''is much faster than the first time.'' ''if something fails part way through creating an environment, such as not removing the pip install for sasview & sasmodels, then "update" will be faster e.g.'' conda env update -f=/path to your new yml file/conda_py3_qt5_new.yml --name qt5 ''If it does not work the first time through, try going back to the normal sasview master, then repeat the steps above. Piotr and others will be making this easier in the future.'' == [=#anchor1 Step 7 - Install Git (Optional)] == Install Git for your platform by following instructions: {{{ https://git-scm.com/book/en/v2/Getting-Started-Installing-Git }}} When installing on Windows, it may be worthwhile to make sure "Use Git from the Windows Command Prompt" is selected, rather than "Use Git from Bash only". This way you can use git from the same command line as you will use Anaconda. Set up your credentials: {{{ git config --global user.name "John Doe" git config --global user.email johndoe@example.com }}} If you work behind proxy remmber to configure {{{ e.g. git config --global http.proxy 192.168.1.1:XXXX }}}
