Conda Python script not getting right command line argument

Conda Python script not getting right command line argument

[ravi r]

Using

Cygwin Python interpreter invoked from shebang line
    $ cat /tmp/script1
    #!/usr/bin/python

    print("hello");
   $ /tmp/script1
    hello
    $
works as expected.


Conda Python interpreter invoked from shebang line
    $ cat /tmp/script2
    #!/usr/local/anaconda3/python

    print("hello");
    $ /tmp/script2
    C:\cygwin64\usr\local\anaconda3\python.exe: can't open file
'C:\\tmp\\script2':
    [Errno 2] No such file or directory
    $
fails to get the right path of the input file to execute. The correct
path that should been
passed to the Conda interpreter would have been
    c:\cygwin64\tmp\script2

Version of cygwin being used
    base-cygwin                                         3.8-2

Package base-cygwin has its own version and only helps setup the first install.

Cygwin version can be shown by running uname -a or head /proc/version.

Cygwin supports running scripts using Cygwin paths with Cygwin interpreters.
Cygwin executes Windows executables directly, and does not convert Cygwin paths 
into Windows paths: you have to set the paths up to make them correspond, or 
provide an appropriate argument for a Windows executable.

As Anaconda is a commercial Windows product, you have to change those python 
scripts to use Windows paths acceptable to that product, run from a Windows 
shell, using Windows Open with... file associations.
Anaconda product support can help you with setup and changes needed.
