Incompatibility with version of CategoricalArrays about dataframes HOT 4 CLOSED

Hm, I just tried running this and was unable to replicate the issue. Perhaps the issue is that you are not running the notebook with the correct Manifest and Project files?

My Pkg.status() does not give me as many entries as this and it should be using the Manifest and Project files from this repo not the main ones in your julia folder which it seems to be pointing to.

I would make sure you cd() into the correct folder. CC @bkamins We should point people to download the entire repo here right?

from dataframes.

Yes - you should download the whole repository and run it from the folder where you have downloaded the files.

This is exactly the purpose of running https://github.com/JuliaAcademy/DataFrames/blob/master/1.%20Environment%20setup.ipynb part to make sure that you have the proper environment set up. You should get the output exactly as shown there.

Now regarding your output note that you have:

• DataFrames.jl version 0.20.2
• you do not have CSV.jl installed
• you have not activated the project environment, but rather you are using the default environment

If you check the Manifest.toml in the repository of the tutorial you will see that in particular:

• DataFrames.jl is required to be in 0.21 version
• CSV.jl needs to be installed in 0.6.2 version

Note that if you are in the correct directory Jupyter Notebook will automatically use Project.toml and Manifest.toml files I have shared. I also have recently written up a small post explaining how to make Julia REPL to do the same here: https://bkamins.github.io/julialang/2020/05/10/julia-project-environments.html.

I had changed to the directory with the data-frame tutorials, but I can no longer reproduce the problem. Everything seems to run fine now. Thank you!
