从 VBA（或命令行）启动 Anaconda 提示

Question

So far I was being able to launch my python scripts using Excel VBA by doing something like this:

Sub ratesmarkup()
Ratespath = "python " & """S:\Market Risk\Middle Office\Corporate Treasury\Politique Investissement\Python\JTD\Rates Markup.py"""
Cmd_Line = Shell("cmd.exe /S /K" & Ratespath & "&" & "exit", vbHide)
End Sub

Which was working perfectly fine until now. I started testing using Anaconda for a new script and my new script uses the pyxlsb module that I imported via Anaconda as I couldn't use that module with regular PyCharm. Long story short, I want to know how could I modify this script to launch the Anaconda prompt instead of the regular cmd.exe Command Line.

When I launch this into the Anaconda Prompt it works:

python "S:\Market Risk\Middle Office\Corporate Treasury\Politique Investissement\Python\PCBONDS.py"

But when I try launching it from regular Command Line it gives me this error in the terminal:

"ValueError: Unknown engine: pyxlsb"

Yet when I try to install the said pyxlsb module (although I already have it to my knowledge), it says:

Requirement already satisfied: pyxlsb in c:\python\python-3.5.1\lib\site-packages (1.0.6)

The python on Anaconda is 3.7 while the regular one is 3.5. I am using the pyxlsb engine in this manner:

 pandas.read_excel(engine = "pyxlsb") 

Which if I understood requires a certain version of Python, that is provided to me through Anaconda. This is at work so I can't just install a different version of standalone Python just like that. So basically is there any possible way of being able to launch the anaconda based python script through VBA by modifying my currently already existing sub? Can't find nothing that answers this directly.

Thanks!!

Answer 1

You need to start virtual environment first.second step is run your script inside the virtual environment.create a batch file including all the steps you need to execute and execute batch file through your VB script. lets say your windows user is TMF and your virtual environment is myenv .

batch file

@echo on
set root=C:\Users\TMF\Anaconda3
call %root%\Scripts\activate.bat %root%
call activate myenv
"C:\Users\TMF\Anaconda3\envs\myenv\python.exe" "S:\Market Risk\Middle Office\Corporate Treasury\Politique Investissement\Python\PCBONDS.py"
pause

Answer 2

To those who like conclusions lol.

My.bat file ended up looking like this:

@ECHO ON
set root=C:\Users\%1%\Anaconda3
call %root%\Scripts\activate.bat %root%
call activate "S:\Market Risk\Middle Office\Corporate Treasury\Politique 
Investissement\Python"
"S:\Market Risk\Middle Office\Corporate Treasury\Politique 
Investissement\Python\python.exe" "S:\Market Risk\Middle Office\Corporate 
Treasury\Politique Investissement\Python\PCBONDS.py"
PAUSE

Where the %1% holds the value of the variable that I will pass through my VBA script, in this case the username of the user currently using the PC.

The VBA script looks like this:

Sub VABONDS()
User = Environ("UserName")

batpath = "pushd " & """S:\Market Risk\Middle Office\Corporate Treasury\Politique 
Investissement\Python\"""
bathfile = "PCBONDS.bat "

Set CMD = VBA.CreateObject("WScript.Shell")
CMD.Run "cmd.exe /S /K" & batpath & "&" & bathfile & User & "&" & "exit", 
vbNormalFocus, True

End Sub

Where the User = Environ("UserName") allows me to get the username of the user dynamically.

Just thought I would share as it could help others !!
