I'm trying to create a POMDP model and solve it. But during the solving process, I get this error:

I'm not so familiar with the Julia Stacktrace, so could you please help me fix this problem?
Caused by stateindex(...) and states(...) wrong implementation in my POMDP model. But after I fix this ans start to solve the problem, the solving just kept run and finally failed. Just want to complain, Julia POMDP is really hard to use in reality...

I am a postgraduate majoring in physics. I am interested in computing and programming. From my classmates the julia lang is a programming language facing futrue because of its advanced programming philosophy. However, what I did not expect is that I meet the problem I can not resolve so soon. (This paragraph is for the prompt "Most is code, please add more details")
I do not even know what have happened till now. However I find the solution for my question and I have succeed in resolving it. Having excute Pkg.add("Plots"), just excute the following codes:
using Pkg
Pkg.add("GR")
Pkg.build("GR")
Pkg.precompile()
The answer is from here

I tried to add a new environment user path as JULIA_HOME to the following route:
C:\Users\madel\Julia-1.7.2\bin and works now. It seems like I was not pointing the right path.
I am experiencing slightly strange behaviour from a visualisation routine I have written using Plots.jl. The module I have written uses code of the following form (with some irrelevant details removed). It is intended to produce a 2D animation of the results of a 2D partial differential equation.
anim = #animate for (i,u) in enumerate(sol.u)
heatmap(u)
end
gif(anim,"output/anim_u.gif",fps=5)
If I run my program with this code at the end, the program hangs indefinitely after opening a "gksqt" application in the dock. Killing the program produces the following stacktrace.

I am completely baffled by this behaviour - if anyone has any suggestions it would be greatly appreciated.
Running on MacOS 11.2.3 with Julia 1.6.2.
I am trying to save a large variable in Julia resulting from a long computation as a file, so I can load the variable later on without recomputing it. When I load the variable I get an exception. I'm storing the file using the JLD library for Julia. I compute the variable using the library Eirene, which performs topological data analysis. The resulting file is 173MB.
I've looked this up and I couldn't find anything about this error message online. I was worried at first that the file was corrupted or something due to insufficient space but that's not the case.
This is the offending code:
using Eirene
using JLD
C = load("/path_to_file/file.jld")["filtration"]
And here is the code where I save the file:
using Eirene
using JLD
C = eirene("/path_to_distance_matrix/dmat",maxdim=3)
save("/path_to_file/file.jld", "filtration", C)
eirene basically builds a series of triangular structures based on the distances between points in a distance matrix I give it. The distance matrix in particular is very dense, causing a long triangle-building calculation.
You can access the distance matrix in this gist if you want to reproduce this problem. The calculation takes me 30min on my laptop.
I get the following error message (the file get_class_reps is the one that contains the first code snippet above).

You've probably already fixed this, but if anyone else runs into this problem, switching from JLD to JLD2 fixed this for me. All that needs to be done is change using JLD to using FileIO and change all extensions in the save and load calls from .jld to .jld2.
