Hi,
Because I can’t, I am inside a Jupyter notebook cell, which start elixir kernel…
(https://github.com/pprzetacznik/IElixir)
So, I move to Code.append… and get true !
When you have a project created with mix and want to use Code.append_path, which directory you have to use ? (I took the ebin, but there are many directories in the build folder)
To illustrate my errors:
Two examples from DataFrame project with two errors:
A/
[1] Code.append_path “/Users/arnaudgarcia/Documents/dev/elixir/dataframe/_build/dev/lib/dataframe/ebin”
true
[2] # trying a dataframe creation example
data = DataFrame.new(DataFrame.Table.build_random(6,4), [1,3,4,5], DataFrame.DateRange.new(“2016-09-12”, 6))
%Inspect.Error{message: “got ArgumentError with message “column is not of the right dimmension” while inspecting %{struct: DataFrame.Frame, columns: [~D[2016-09-12], ~D[2016-09-13], ~D[2016-09-14], ~D[2016-09-15], ~D[2016-09-16], ~D[2016-09-17]], index: [1, 3, 4, 5], values: [[0.905774885481212, 0.4351008822922161, 0.7303435227541554, 0.9129132766344731], [0.8350586706543478, 0.0016607496087180929, 0.007627583799604487, 0.22343284746603354], [0.517801966022468, 0.495824436700939, 0.3998929400604335, 0.8614117714039994], [0.5539917967005131, 0.31485805275150314, 0.32484346729178115, 0.7137779856957303], [0.5460843983259391, 0.7475024600080701, 0.14066542500009394, 0.48414344094246653], [0.8022460995239326, 0.8935898429649934, 0.3368457680971688, 0.6024761078856264]]}”}
