Missing modules

[x75]

When I try to run your text files(sphero_raw.py or shpero_res_learner_1d.py, e.t.c...) I get the error message: No module named reservoirs

[x75]

first one is smp_msgs.msg.reservoir

quick fix is to git clone smp_msgs repository into your ros-workspace/src and run catkin

cd ws-kinetic-py3/src
git clone git@github.com:x75/smp_msgs.git
cd ..
catkin_make_isolated install

better but more effort is to replace the reservoir message with just FloatArray from std_msgs, didn't know back then.

[x75]

second one is you'll need Reservoir class from reservoirs.py, which has moved to smp_base and become smp_base.models_reservoirs. smp_base is available as well but you'd need to edit the imports.

queued and WIP, will be back with fixes but may take a bit

Thank you for your reply. I will work on this right now

I have updated the import statements. But a new error comes up:

ImportError for rlspy
("Couldn't import init_jpype from measures_infth, make sure jpype is installed", ImportError('No module named config',))
Traceback (most recent call last):
File "src/smp_sphero/sphero_res_learner_1D.py", line 21, in
from smp_base.models_learners import learnerEH
File "/home/neville/Ros_Workspace/src/smp_base/smp_base/models_learners.py", line 702, in

@dec_compute_infth_soft()
NameError: name 'dec_compute_infth_soft' is not defined.

I assumed perhaps that I didn't have the jpype installed but I ran :

sudo apt-get install python-jpype
but the error persists. Any advice on this issue?

sorry for the mess and thx for patience, let me try and fix the packages deps today, be back when done sometime tonight.

[NevilleKitala]

Appreciate the speedy reply. Many Thanks.

[x75]

are you on py2 or 3?

[NevilleKitala]

I'm using py2

[x75]

replaced offending imports, if you have smp_base in your PATH it might just work. lmk.

[NevilleKitala]

I'm going to try it now. Thank you

[NevilleKitala]

I would like to report that this error persists. I had updated the local repository I had originally pulled. The issue is in model_learners:

line 794, in learnerReward
@dec_compute_infth_soft()
NameError: name 'dec_compute_infth_soft' is not defined.

The system recommendations were to install jpype but I already have that installed.

[NevilleKitala]

Please explain what the @dec_compute_infth_soft() function does.

[x75]

ah seems i forgot about the second issue. you'll need jpype, infodynamics.jar from JIDT, and then create a config.py in from config.py.dist in smp_base/smp_base. the config has the path to the jar file.

[x75]

i'll fix along and push
