# Installing the tested pipeline stack

Conda (miniconda3 or anaconda3) must already be installed, if it is not,
'Advance Setup' below.
All steps must be performed in bash or a compatible shell.

A fresh installation of Anaconda3 or Miniconda3 is not required for each JWSTDP
release. The method described here allows for multiple, entirely segregated,
pipeline installations.

## Linux
To reproduce the environment used during JWST prerelease testing on Linux, a 
three-step installation process is required.

1) Install the target python interpreter and its dependencies using conda, then
```
$ conda create -n jwstdp-1.3.2 --file
https://ssb.stsci.edu/releases/jwstdp/1.3.2/conda_python_stable-deps.txt
```

2) Activate the environment
```
$ source activate jwstdp-1.3.2
```

3) Install the pipeline software packages on top using `pip`:
```
$ pip install -r https://ssb.stsci.edu/releases/jwstdp/1.3.2/reqs_stable-deps.txt
```

## Macos
To reproduce the environment used during JWST prerelease testing on Linux, a 
three-step installation process is required.

1) Install the target python interpreter and its dependencies using conda, then
```
$ conda create -n jwstdp-1.3.2 --file
https://ssb.stsci.edu/releases/jwstdp/1.3.2/conda_python_macos-stable-deps.txt
```

2) Activate the environment
```
$ source activate jwstdp-1.3.2
```

3) Install the pipeline software packages on top using `pip`:
```
$ pip install -r https://ssb.stsci.edu/releases/jwstdp/1.3.2/reqs_macos-stable-deps.txt
```

# Advance setup
 
If conda has not yet been installed, use the following steps to obtain
it, then use the procedure above to install the pipeline software.

For detailed instructions of this step, please visit: http://docs.continuum.io/anaconda/install#linux-install

**For Miniconda:**

```
$ wget
https://repo.continuum.io/miniconda/Miniconda3-Latest-Linux-x86_64.sh
$ bash Miniconda3-Latest-Linux-x86_64.sh
$ export PATH=$HOME/miniconda3/bin:$PATH
```

**For Anaconda (if preferred):**

```
$ wget
https://repo.continuum.io/archive/Anaconda3-2019.10-Linux-x86_64.sh
$ bash Anaconda3-2019.10-Linux-x86_64.sh
$ export PATH=$HOME/anaconda3/bin:$PATH
```
