Install in RHEL 8.2

[vikramkhatri]

I switched to Python 2.7 on my RHEL 8.2

# /usr/bin/python --version
Python 2.7.17

# pip --version
pip 9.0.3 from /usr/lib/python2.7/site-packages (python 2.7)

When I try to install RPM.

# rpm -ivh pcircle-0.17.1-1.el7.noarch.rpm
error: Failed dependencies:
	python >= 2.7 is needed by pcircle-0.17.1-1.el7.noarch
	python-cffi is needed by pcircle-0.17.1-1.el7.noarch
	numpy is needed by pcircle-0.17.1-1.el7.noarch
	python-scandir is needed by pcircle-0.17.1-1.el7.noarch
	pyxattr is needed by pcircle-0.17.1-1.el7.noarch

A couple of above are already there. For example:

Sorry - I know very little about Python. Any help is appreciated as to what might be the issue and how to solve it?

Thank YOU

@vikramkhatri the rpm is built for redhat/centos 7, so the dependencies will be broken on redhat 8.

Please try this

Dependencies

sudo yum install -y redhat-rpm-config python2-devel openmpi-devel

Load MPI into the environment you may have to start a new terminal for module to work

module load mpi

Install from Github

pip2 install --user future
pip2 install --user git+https://github.com/olcf/pcircle

the --user is meant for unprivileged user install, it will install to ~/.local/bin, you need to have that in the PATH. If the above steps are good, then you should be able to run "fcp" or "fprof". And if you want to try muli-process either on a single node or multiple nodes (all needs to have MPI setup) you can do mpirun -np 8 fcp ...

Thank you so much. I will try it out.
