I initially would like to use PyPlot. The error message prompted me to rebuild PyCall. V1.4, Windows 7 x64. I then use this command using Pkg Pkg.build(“PyCall”) But it did not solve the problem. I was unable to build PyCall. The error message is below: julia> using PyPlot [ Info: Precomp…

Steven, Thanks. I force Julia v1.4 to use the installed Python 64-bit version. I added Matplotlib to the installed Python (64-bit) Add the command using Pkg;Pkg.build("PyCall") Now, I am able to use PyCall and PyPlot on my windows 7 x64. Thanks for your time.

Hi, Do I need to add miniconda package to resolve this problem?

I installed Python V3.8 on windows 7 x64 and would like to rebuild PyCall. I added PyCall package. I changed the global variable ENV ENV[“PYTHON”] = “D:\programs\python\v38\python.exe” Then I use the command using Pkg;Pkg.build(“PyCall”) I got the following error. Julia v1.4 cannot find Py…

ErrorException("D:\\programs\\python\\v38\\python.exe is 32-bit, but Julia is 64-bit") As the error message says, your Python is 32-bit. You can’t link 32-bit Python to 64-bit Julia.

could you try this? @fhkm ENV[“PYTHON”] = “D://programs//python//v38//python.exe” the day before yesterday I again worked with PyCall, and this problem occurred once again, IIRC.

Yes, I tried that. It did not work.

I merged the two threads. You have two choices: If you want to use a pre-existing/manual Python installation via ENV["PYTHON"], then you need to install a 64-bit Python for a 64-bit Julia, or switch to a 32-bit Julia to link to a 32-bit Python. If you want Julia to install its own Miniconda d…
