Re: Erroroccur: NameError: name 'ax' is not defined

[Jean-Noël Grad]

Dear Chandra,

From my side, the following commands produced plots and videos without raising a name error:

make tutorial_11_1_python
mpiexec -n 4 ./pypresso doc/tutorials/11-ferrofluid/11-ferrofluid_part1.py

Same observation when exporting the notebook to a python file from the Jupyter client. Could it be possible that the instruction "fig, ax = plt.subplots(figsize=(10,10))" at line 159 was accidentally deleted, or indented it such that it becomes part of the function "run()" declared above?

Best regards,
Jean-Noël Grad

Dear all,

When i am running 11-ferrofluid-part1 by saving a python file in my system using mpirun -np 4 pypresso script.py an error is coming.

 

Error is                                                                 

   quilibration done
Traceback (most recent call last):
  File "test.py", line 160, in <module>
    part, = ax.plot([],[], 'o')
NameError: name 'ax' is not defined

The code is

   fig, ax = plt.subplots(figsize=(10,10))
part, = ax.plot([],[], 'o')

animation.FuncAnimation(fig, run, frames=loops, blit=True, interval=0, repeat=False, init_func=init)

Thanks & Regards
