PostProcess in Centos about smilei HOT 11 CLOSED

Hi

You seem to have run the happi.Open command in your bash terminal. However, this is a python command.

You first need to install the happi package: in a bash terminal, type make happi from the original Smilei directory. This has to be done only once in your machine. You should see a message saying a smilei.pth file was added somewhere. Otherwise, it means something is wrong with your python installation.

Then, open a python prompt using the python command, or any other, such as ipython which I recommend. In this prompt, you have to import happi then you may run command happi.Open as you did above.

I would like to add that the resolution to your problem is already explicit in the documentation.

If the doc is not clear for you, please explain what it lacks.

Dear @mccoys ,

Thanks for your e-mail and sorry that I did not look to the documentation.
I tried to install happy, by typing make happi in the shell but I could not,
I tried to execute Diagnostics.py file as follows, but seems still error exists:
(maybe it is due to my system, I use devtoolset -3 for GCC 4.9, but python is with GCC 4.8.5)

execfile("/home/work/Smilei-master/scripts/Diagnostics.py")
S = happi.Open("/home/work/Smilei-master")
Traceback (most recent call last):
File "", line 1, in
NameError: name 'happi' is not defined

You need to type make happi in the smilei follder.

cd  /home/work/Smilei-master
make happi

what the above lines return?

from smilei.

However it seems that point 2 in https://smileipic.github.io/Smilei/installation.html#install-the-happi-module is no more valid for the latest release.

@mccoys can you confirm?

Dear @iltommi @mccoys ,

Thanks and sorry.
I used the previous version of Smilei and there was no happi folder, I compiled the new version and now I can use happi, ^_~

@iltommi the Diagnostics.py technique should still work

@bitalm indeed the module happi is new and you need the newest version of smilei :)

I get this error when trying to directly import happi

In [1]: execfile("happi/__init__.py")
---------------------------------------------------------------------------

@iltommi but this is not the right file to import. You must import scripts/Diagnostics.py

from smilei.

Dear @mccoys and @iltommi ,

Also I think I need h5py, when I run the
S = happi.Open("/home/work/Smilei-master/tst2d_4_laser_wake")
I receive as:
Traceback (most recent call last):
File "", line 1, in
File "/home/work/Smilei-master/happi/_core.py", line 512, in Open
return SmileiSimulation(*args, **kwargs)
File "/home/work/Smilei-master/happi/_core.py", line 538, in init
import h5py
ImportError: No module named h5py

Dear @mccoys and @iltommi

I could solve the issue of h5py using anaconda python I guess,
Thanks :)
All The Best
