Question

I'm following the retrieve and rank tutorial and everything is good until the train.py script - I get an error message below:

Generating training data...
Traceback (most recent call last):
  File "./train.py", line 83, in <module>
    process = subprocess.Popen(shlex.split(curl_cmd), stdout=subprocess.PIPE)
  File "C:\Python27\lib\subprocess.py", line 710, in __init__
    errread, errwrite)
  File "C:\Python27\lib\subprocess.py", line 958, in _execute_child
    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

Any ideas?

@peter-wood answered the question in the comments.

In this case, the unfriendly error message:

WindowsError: [Error 2] The system cannot find the file specified

was caused by curl not being on the PATH. train.py expects the curl command to be available and on the PATH.
