Examples not running due to modules not being found
jam474cwru opened this issue · comments
Description: Hello. I am new to the use of PyElastica and haven't coded in some time. I am trying to learn this open source software and run the examples to understand and learn from both the binder and examples folders. However, no matter how many times I try to address the errors, I always am told the beginning modules are not found with the ModuleNotFound error. It is quite frustrating and confusing especially since I would expect them to be within the software already. I am particularly just wanting to start by learning the binder examples and the timoshenkobeamcase and muscularsnake examples.
To reproduce, all I have simply done is copy the exact code from github and cloned a repository in Visual Studio Code.
Expected Behavior: ModuleNotFound
Based on the first image you shared check if you have installed PyElastica correctly. Make sure to create a conda environment with python 3.10. Then install pyelastica doing pip install pyelastica . I suggest also install example dependencies pip install "pyelastica[examples,docs]" .
Based on second image python cannot find the paths, I suggest appending paths.
import sys
sys.path.append("/")
sys.path.append("../")
sys.path.append("../../")@armantekinalp Thank you for the response, Arman. I installed and created the conda environment with python 3.10 and ran those couple initial installations of pyelastica. I even did the second recommendation in relation to the path, but did not have any luck. I copied that code in a separate file as well and even tried in front of the timoshenko example. Any other recommendations?
@armantekinalp I have even tried:
import sys
sys.path.append(r"c:\Users\jmegu\PyElestica\PyElastica\examples\TimoshenkoBeamCase\timoshenko.py")
thinking that this is the path I must fix, but nothing has worked.
If you are using VScode, try enabling this option in the settings. You can find it by searching for python terminal in the settings.
Unfortunately, the same outcome after I enabled that in settings. I even created a new window and folder and cloned the code from the repository all over again. I installed pyelastica and the initial steps again, but don't understand why this is happening.
Please keep the
import sys
sys.path.append("/")
sys.path.append("../")
sys.path.append("../../")I believe this worked in running the initial codes. Thank you. However, what is the requirements to run a movie? In the muscular snake example, I ran the code for multiple days and by the end it was not able to do anything as it had a runtime error and issue with a needed requirement for a software for any sort of movie. Is there an extension that is needed for these final plots to work?
Unfortunately I killed the terminal so I couldn't post a picture as it ran the simulation again automatically.
do this pip install "pyelastica[examples,docs]" to install example dependencies. Before running the whole simulation change final time to something small and make sure you can generate the videos. Then run the whole simulation.
Upon trying this, I get this error:
Do conda install ffmpeg
Seems there is an OS error of not having a "seaborn-whitegrid" file. Are these common errors that are often experienced?
Can you check you matplotlib version? Seems like seaborn-whitegrid is depreciated. You can install matplotlib version 3.7.5 or you can checkout the branch update-0.3.2 , I fixed it there.
I was able to install that version and it worked... super cool to be able to visualize it. What is the best way to save work? I am struggling downloading the mp4 videos and saving.
what do you mean? mp4 videos should be saved in the same directory as the snake file.
I was able to get the videos. Thank you.
I particularly would like to inquire about the muscular snake example. What is the difference between nu and poissons ratio when defining the bodies? what about n_elem_body? How are the force amplitudes determined and for which muscles?
I really appreciate your help through these questions.
@jam474cwru I am closing this issue since this particular problem seems to be resolved. If you have further questions, please open another issue/discussion.
I believe the answer for the questions that you are asking can be found in the tutorials, I would recommend to check tutorial: theory and tutorial: numerics.
