configuring jidt with jpype for info theoretic measures

[x75]

jpype fails to import because infodynamics.jar is not found

depending code may fail breaking the script

[x75]

check smp_base/README and make sure you have installed, downloaded and configured all the components

[NevilleKitala]

I have followed the installation instructions you have prescribed for smp_base.
With my file structure as follows:

smp_base:
-.git
-doc
-infodynamics:
--infodynamics.jar
-smp_base:
--config.py
-vendors:
--rlspy

I am still getting an error about infodynamics not being found. This might be an issue with how i have written the config.py file:

Imported RLSPY ./vendor/rlspy/
Couldn't import emd from emd with No module named emd, make sure emd is installed.
Traceback (most recent call last):
File "src/smp_sphero/sphero_res_learner_1D.py", line 15, in
from smp_base.models_learners import learnerEH
File "/home/neville/ROS/src/smp_base/smp_base/models_learners.py", line 34, in
from smp_base.measures_infth import init_jpype, dec_compute_infth_soft

init_jpype()
File "/home/neville/ROS/src/smp_base/smp_base/measures_infth.py", line 60, in init_jpype
assert os.path.exists(jarloc), "Jar file %s doesn't exist" % jarloc
AssertionError: Jar file ./infodynamics/infodynamics.jar/ doesn't exist

the config file that I created looked like this:

RLOC='./infodynamics/infodynamics.jar'
RLSPY='./vendor/rlspy/'

Any advice would be appreciated.

try to set absolute path in config.py, e.g.

JARLOC=/home/neville/ROS/src/smp_base/infodynamics/infodynamics.jar

[NevilleKitala]

Thank you that seems to have cleared that error up.
The program now runs upto openning the cfg filed in sphero_res_learner_1D. THe issue is this:

I am sorry for all this inconvenience.

where do run the script from, pwd?

[x75]

you'll need to be in the smp_sphero/ directory. for each of the two 1D and 2D scripts there's a directory with the same name, that contains the config files

[x75]

the parser says: nosectionerror because the file isn't found.

sorry as well but happy to try and fix as long as you can maintain motivation 😅

[x75]

referring back to x75/smp_sphero#2

[NevilleKitala]

I have it running at the moment. Thank you for your time. I will keep you posted on my progress!

[x75]

wow, great. please do post, quite curious.

need to merge your feedback into install docs. hopefully more significant updates in smp installation, docs and code soon.

also, smp_sphero is obsolete / legacy code, planning to recreate the functionality in a more general way within smp project.
