Python <-> Cadence using ipc not reading files

It works for me. Which IC version are you using (what does getVersion(t) return in the CIW)? I do see an issue if running (say) python v2 from IC23.1 that if I do:

id=ipcBeginProcess("myPythonCommand")
ipcWait(id)
ipcReadProcess(id)

I get:

"Could not find platform independent libraries <prefix>\nCould not find platform dependent libraries <exec_prefix>\nConsider setting $PYTHONHOME to <prefix>[:<exec_prefix>]\n"

If it's that, you could just run:

d=ipcBeginProcess("runUserCmd myPythonCommand")
ipcWait(id)
ipcReadProcess(id)

The runUserCmd restores the PATH and LD_LIBRARY_PATH etc back to what it was before Virtuoso started.

Thank you for the reply.

I'm using ICADVM20.1-64b
Python is 2.6.6.

Also, I was already using ipcWait:
ipcWait(ipcBeginProcess(strcat("python " x " " y ".temp") "" "" "" "" "CDS.log_py"))

x is the python script
y.temp is the input file.
y.temp_temp is the copied contents from y.temp using python

For some reason, when I run x in terminal, the y.temp_temp has contents.
When ran using ipc, y.temp is not being read, and there is no output in y.temp_temp

I just threw together this simple python script:

#!/usr/bin/env python
import argparse
parser = argparse.ArgumentParser(description='Simple file copier')
parser.add_argument('inputFile', type=str,
                    help='Input filename')
args = parser.parse_args()

data=open(args.inputFile).read()
newFile=open(args.inputFile+"_temp","w")
newFile.write(data)
newFile.close()

and then this SKILL:

x="readfile.py"
y="file"
ipcWait(ipcBeginProcess(strcat("python " x " " y ".temp") "" "" "" "" "CDS.log_py"))

and file.temp_temp was created with the same contents as file.temp. Was anything in the CDS.log_py? If an error occurred, you should see it there (I forced an error, such as giving a file that didn't exist, and it reported this there).

This is my python code:

import os
import sys

s = open(sys.argv[1]).read()
print("Test Below")
print(s)
print(os.getcwd())
print(sys.argv[1])

sys.argv[1] should be y.temp. y.temp contents are:

a 1
b 2
c 3
d 4

CDS.log_py contents are:

Test Below

<working_directory>
<y.temp>

Yes, s was not output. Items with <> are censored for privacy reasons, but these values were correct. It's just that s does not have any contents.

I just tried your code, and it works for me (I'm using ICADVM20.1-64b.500.34 and python 2.7.5 but I'd be surprised if that mattered)

Test Below
a 1
b 2
c 3
d 4
