Training a ranker with train.py script

Question

I'm currently trying to create a ranker by running the train.py script provided by the Retrieve & Rank Documentation.

I issue the following command when trying to create the ranker:

train.py -u usernameHere:PasswordHere -i  Mainframe_Batch_Automation_CA7.csv -c clusterIdHere -x Mainframe_Batch_Automation_CA7 -n Mainframe_Batch_Automation_CA7

And I receive the following error:

Input file is Mainframe_Batch_Automation_CA7.csv
Solr cluster is sc0c2398d4_d087_4516_99dd_10c25cc06b0a
Solr collection is Mainframe_Batch_Automation_CA7
Ranker name is Mainframe_Batch_Automation_CA7
Rows per query 10

Traceback (most recent call last):
  File "C:\Users\IBM_ADMIN\Documents\Retrieve & Rank\train.py", line 83, in <module>
    process = subprocess.Popen(shlex.split(curl_cmd), stdout=subprocess.PIPE)

    errread, errwrite)
  File "C:\Python27\lib\subprocess.py", line 640, in _execute_child
    startupinfo)
WindowsError: [Error 2] The system cannot find the specified file

At first I thought it was because Python wasn't in my PATH environment variable but after adding it to the PATH variable it still gives me the same error ...

Answer 1

Script runs curl command which connects to solr and ranker urls. This error is due to firewall issues. Try to execute the script outside firewall.
