Installation¶
Anaconda (recommended)¶
ESPEI does not require any special compiler, but several dependencies do. Therefore it is suggested to install ESPEI from conda-forge.
conda install -c pycalphad -c msys2 -c conda-forge --yes espei
After installation, you must turn off dask’s work stealing.
Change the work stealing setting to distributed.scheduler.work-stealing: False
in ~/.config/dask/distributed.yaml
.
See configuration below for more details.
PyPI¶
Before you install ESPEI via PyPI, be aware that pycalphad and emcee must be compiled and pycalphad requires an external dependency of Ipopt.
pip install espei
After installation, you must turn off dask’s work stealing.
Change the work stealing setting to distributed.scheduler.work-stealing: False
in ~/.config/dask/distributed.yaml
.
See configuration below for more details.
Development versions¶
You may install ESPEI however you like, but here we suggest using Anaconda to download all of the required dependencies. This method installs ESPEI with Anaconda, removes specifically the ESPEI package, and replaces it with the package from GitHub.
git clone https://github.com/phasesresearchlab/espei.git
cd espei
conda install espei
conda remove --force espei
pip install -e .
Upgrading ESPEI later requires you to run git pull
in this directory.
After installation, you must turn off dask’s work stealing.
Change the work stealing setting to distributed.scheduler.work-stealing: False
in ~/.config/dask/distributed.yaml
.
See configuration below for more details.
Configuration¶
ESPEI uses dask-distributed to parallelize ESPEI.
After installation, you must turn off dask’s work stealing!
Change the file at ~/.config/dask/distributed.yaml
to look something like:
distributed:
version: 2
scheduler:
work-stealing: False
See the dask-distributed documentation for more.
