I had installed octave version 4.2.1 and loaded the symbolic package on a windows 10 PC (64 bit OS). But when I run "syms x" to test if the package is working, I get the error:
/"Closing the Python pipe...
error: ipc_popen2: something unexpected has gone wrong in starting python
/
/error: called from
          python_ipc_popen2 at line 138 column 7....."
/

I have python 2.7 installed
 I tried adding the path of my python installation library "C:\Python27" under "Path" inside environmental variables, but not helping unfortunately.

It'd be great if someone could share their thoughts on what may be wrong here, or a workaround

Some thoughts:

1. From looking at the code, it seems where should be more output (the values of "A" and "out" for example. Can you report those too?

2.  What does "sympref python" report?

3.  Does something like "setenv PYTHON C:\Python27\bin\python" help?

4.  Perhaps you should try the bundle package.

5.  There is more notes on Windows installation here:
