Installation on NERSC #24

Open abaleato opened 5 years ago

abaleato commented 5 years ago

Hi all,

I would like to get the code to run on NERSC cori as a first step towards being able to use pixell.

So far, I have been able to successfully follow the instructions provided in the README file, culminating in the creation of a libsharp/auto folder with the installation. However, trying import sharp from a python interpreter fails at this stage. To try to remedy this, I have tried python setup.py install from the libsharp/python directory, obtaining the following output and error message:

I don't know if this is relevant information, but I made sure to be using gnu compilers before I started by entering module unload PrgEnv-intel module load PrgEnv-gnu

Any ideas on how to solve this would be much appreciated.

Thank you very much,

Anton

Can you try adding -fPIC to CCFLAGS_NO_C and CLFLAGS in the config.auto file and recompiling?

abaleato commented 5 years ago

Thank you very much for your fast response.

I just tried your recommendation, and although the error message is different, we're still not quite there.

To be clear, what I did was: 1) delete my libsharp directory, clone it again. 2) follow the instructions in the readme, making sure to add -fPIC to CCFLAGS_NO_C and CLFLAGS in config/config.auto before running make. 3) define LIBSHARP=/global/homes/a/ab2368/Software/libsharp/auto/, then export LIBSHARP. 4) Finally, cd python and then python setup.py install, after which I obtain the following error message:

even recompiling with ./configure --disable-mpi --enable-pic does not do it... I shall keep trying.

Thanks again for your help!

Sorry, I fear I'm not familiar enough with the Python<->C ecosystem to provide any useful input. @dagss, any insight?

Did you find a way to handle that error ?

Thank you, Gabriel.

Gabriel-Ducrocq commented 4 years ago

I finally found a temporary way around this:

After adding -fPIC to CCFLAGS_NO_C and CLFLAGS in the config.auto file and recompiling, I removed the libsharp_mpi extension from the setup.py file.

Then I ran python setup.py install and everything went fine. But when I tried: import libsharp I got the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/gducrocq/libsharp/python/libsharp/__init__.py", line 1, in <module> from .libsharp import * ModuleNotFoundError: No module named 'libsharp.libsharp'

It seems that's because the folder of the module in the site-packages of my environment was named libsharp-0.1-py3.7-linux-x86_64.egg. Renaming this folder as libsharp made the trick, and now I can import it and use it.

I guess this comes at the cost of efficiency but at least I can test and debugg my code. Hope this helps :)
