I want to install Julia in my jupyter notebook. I am getting this. I am not able to find what means the reference to 'no active Project'. Any help will be very welcomed. Thanks

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.

Julia Version 1.6.6 (2022-03-28). Julia is installed by the installer downloaded from https://julialang.org/downloads/
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 am encountering an error on Julia while trying to install and use Distributions module. I am not facing any errors while installing the module but it displays this error when I try to use the Distributions module. I have no idea what this PDMats or Manifest files are. I'd love to have some advice. Thanks!

I have Julia 1.7.2 and HDF v"0.16.2" on a Windows 10 machine.
I ran into an issue opening an HDF5 file:
using HDF5
raw_hdf_data = h5open("Data_2021-03-17_11-21-19.h5", "r")
obj = raw_hdf_data["Group"]["Data_1"]
HDF5.read(obj)
but got an error:

Thanks very much!
I had the same issue when I updated my HDF5 library.
Probably the file is compressed and one of the following plugins are necessary. Try:
] add H5Zblosc, H5Zbzip2, H5Zlz4, H5Zzstd
using HDF5, H5Zblosc, H5Zbzip2, H5Zlz4, H5Zzstd
raw_hdf_data = h5open("Data_2021-03-17_11-21-19.h5", "r")
...
Now it should open the file.
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'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...
