Issues with Foundations of machine learning Environment

[ankit48365]

I will first share the issues I face and then what I am trying and what issues I am facing, please follow all the steps:

1. Working on Julia academy - Foundation of Machine Learning (https://juliaacademy.com/courses/enrolled/392870)

2. I am using the "Foundations of machine learning" environment as suggested in the beginning of the course.

3. All goes fine until I issue the below command - I get this warning

using Plots;

4. Then this error comes when I issue the next command plot(x -> σ(x, w, b), xlim=(-0,1), ylim=(-0.1,1.1), label="model", legend=:topleft, lw=3)

5. When I try to add anything into the 'Foundation of Machin......' environment I get the below permission error

• add Plots#master • add GR

ERROR: SystemError: opening file "C:\Users\XXXX\.julia\packages\JuliaAcademyData\1to3l\courses\Foundations of machine learning\Project.toml": Permission denied

6. Below is the show status of v1.4 environment and Foundation of Machin...... (notice The later one doesn't even have GR and i cant add to it aswell)

@logankilpatrick @mbauman Hey Guys !! Is there anything you can do to resolve my problem !! will appreciate your help !!!

[YusufMohammedUH]

You can solve the permission issue by changing the permission for the given file. I encountered the same problem and was able to solve this on Ubuntu by doing sudo chmod -R u=rwx ~/.julia/packages/JuliaAcademyData/1to3l/courses/Foundations\ of\ machine\ learning/Project.toml.

I guess you could just use u=rw.

You should additionally import additional libraries with using Images;using ImageMagick;using FFTW In order to avoid additional isssues.

Hey, I just updated the notebooks for this. Should be all good now. Sorry for the delay!
