my code:
using PyCall, Conda
root = Conda.ROOTENV
pipPath = joinpath(root, "bin", "pip")
`$(pipPath) install KMeans_elbow`
Conda.add("KMeans_elbow")
KM=pyimport("KMeans_elbow")
the error:
ERROR: LoadError: failed process: Process(setenv('C:\Users\27990\.juliapro\JuliaPro_v1.4.2-1\Conda_env\Scripts\conda.exe' install -y KMeans_elbow,[“PATH=C:\Users\27990\.juliapro\JuliaPro_v1.4.2-1\Conda_env\Library\bin;C:\Users\27990\.juliapro\JuliaPro_v1.4.2-1\Conda_env\Library\bin;E:\gurobi\win64\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;E:\gurobi\win64;D:\matlab\matlab\runtime\win64;D:\matlab\matlab\bin;D:\matlab\matlab\polyspace\bin;E:\SCIP\SCIPOptSuite 7.0.1\bin;C:\Users\27990\AppData\Local\Microsoft\WindowsApps;”, “USERDOMAIN_ROAMINGPROFILE=DESKTOP-G8OCU62”, “HOMEPATH=\Users\27990”, “PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC”, “NODE_ENV=production”, “SESSIONNAME=Console”, “SYSTEMROOT=C:\Windows”, “APPDATA=C:\Users\27990\AppData\Roaming”, “PSMODULEPATH=C:\Program Files\WindowsPowerShell\Modules;C:\Windows\system32\WindowsPowerShell\v1.0\Modules”, “COMMONPROGRAMW6432=C:\Program Files\Common Files” … “PROGRAMFILES=C:\Program Files”, “LOGONSERVER=\\DESKTOP-G8OCU62”, “DRIVERDATA=C:\Windows\System32\Drivers\DriverData”, “CONDA_PREFIX=C:\Users\27990\.juliapro\JuliaPro_v1.4.2-1\Conda_env”, “ATOM_HOME=D:\JuliaPro\.atom”, “FPS_BROWSER_USER_PROFILE_STRING=Default”, “SYSTEMDRIVE=C:”, “FPS_BROWSER_APP_PROFILE_STRING=Internet Explorer”, “PROCESSOR_ARCHITECTURE=AMD64”, “OPENBLAS_MAIN_FREE=1”]), ProcessExited(1)) [1]
How exactly am I supposed to use PyCall?And use functions in Python? 
thankS!!!
