Cannot build PyPlot

TimeValley · September 22, 2022, 5:48am

Hello everyone, i just started programming julia and encountered a problem.
When I added the PyPlot package and tried to build it:

build PyPlot

It gave those error messages:

Error building `PyCall`, showing the last 100 of log:
`$ C:\Users\Administrator\.julia\conda\3\Scripts\conda-script.py install -y numpy`

An unexpected error has occurred. Conda has prepared the above report.

I"be glad if anyone could share thoughts with me.

I wanted to help you since you’re a new user, but waited to see if others knew this. I don’t know, but I do know a good workaround.

PyPlot.jl isn’t the best plotting package (only the first for Julia I believe).

Makie.jl is likely the best (pure Julia package and can have instant startup, though you might still need a sysimage for that), and the future. Before that there’s a Plots.jl, that abstracts over different backends, e.g. PyPlot.jl, so even if you what to use PyPlot (aka matplotlib), then consider that one.

Despite the name PyPlot ~~isn’t~~ written in Python [EDIT: I see it’s actually “Python 90.7%, C++ 6.5%, […] C 0.2%” the heavy lifting likely done by C/C++ as with all “Python packages”), it’s only a wrapper for Python’s matplotlib (a clone of MATLAB’s plotting). GR.jl (written in C) is the default backend for Plots.jl and I believe it’s better.

If you really want to use matplotlib (or any other Python package) without abstraction, then consider PythonCall.jl (its docs show use of MatPlotLib and another Python plotting alternative seaborn), rather than PyCall.jl (which PyPlot.jl relies on).

I suppose this is a standard error in Conda, still a bit confusing, why would you (indirectly, i.e. Conda) upload, not something you requested:

Sorry for my late reply, I’ve been working on other subjects these days.
I appreciate your kind help. Just like you recommended, I finally gave up trying to use Pyplot and chose other packages.
Here is the full error log:
