Create JPIP CMD

Syntax: obj << Create JPIP CMD()

Description: Triggers the creation of a jpip command line wrapper script for Python's pip command. A directory picker dialog will ask where to save the generated script. This script then provides the full capabilities of pip, while correctly establishing the necessary environment variables for JMP's isolated Python environment.

JMP Version Added: 18

Example 1


// install numpy and pandas packages
conn = Python Connect();
conn << Create JPIP CMD();

Example 2


Python Create JPIP CMD();

Disconnect

Syntax: obj << Disconnect

Description: Note: This function is deprecated as of JMP 18 and has no effect.

JMP Version Added: 14

Execute

Syntax: list = obj << Execute( { list of Inputs }, { list of Outputs }, statements < , echo( 1 | 0 ) > )

Description: Sends a list of inputs, executes statements and returns a list of outputs. Optional echo() parameter defaults to True. The echo parameter controls echoing the Python source to the log. Logical True (1) enables echo of source while 0 suppresses the echo to the log.

JMP Version Added: 14

Example 1


PythonConnection = Python Connect();
// NOTE: a,d,x,z must be declared before Execute()
// as this is the location the results will be written.

z = 0;
v = [1 0 0, 0 1 0, 0 0 1];
// pi, e, phi, c, Plank's, Faraday, 345 triangle
m = [3.141 2.718 1.618,
2.997 6.626 9.648,
3 4 5];
ml = PythonConnection << Execute(
    {v, m, a, d},
    {x, z, a, d},
    "\[
import numpy as np
a = np.multiply(v, m) # matrix product
d = np.divide(v, m) # matrix division
z = np.multiply(m, np.linalg.inv(v)) # m * inv(v) called Left division

Install Packages

Syntax: obj << Install Packages( packages )

Description: This wraps the install of Python packages into the JMP site-packages directory. For operations beyond simple package installation, see Python Create JPIP CMD() to create a command line pip wrapper script in a directory chosen with Directory Pick(). Alternatively, to run the install from a JMP Python script window, look at jmputils.jpip under the Python category here in the Scripting Index.
