Hi all,<div><br></div><div>Due to a recent change in pip and the python package index system doing</div><div><br></div><div>$ pip install mpi4py</div><div><br></div><div>will install mpi4py 0.6.0, a version from 2008.  This is due to a recent decision to only allow pip to download packages from pypi for security reasons.</div>
<div><br></div><div>I&#39;ve raised this issue with the mpi4py developers so hopefully this will be fixed soon.</div><div><br></div><div>For now, mpi4py can be installed via:</div><div><br></div><div>pip install mpi4py --allow-external mpi4py --allow-insecure mpi4py</div>
<div><br></div><div>Or by downloading the source package tarball from the mpi4py package release page on bitbucket and building manually:</div><div><br></div><div><a href="https://bitbucket.org/mpi4py/mpi4py/downloads">https://bitbucket.org/mpi4py/mpi4py/downloads</a><br>
</div><div><br></div>Hope that avoids some confused debugging in the future,<div><br></div><div>Nathan<span></span><br><div><br></div></div>
