[SOLVED] Training a ranker with train.py script

Training a ranker with train.py script

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 ...

Solution

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.
