json reading error json.decoder.JSONDecodeError: Invalid \escape

I am writing a code to upload a model (train_and_upload_demo_model.py) in solr using "config.json" file settings. but I am getting following error: ``` json.decoder.JSONDecodeError: Invalid \escape: line 11 column 34 (char 461) ``` this is the traceback: ``` D:\solr640\contrib\ltr\example>python train_and_upload_demo_model.py -c config.json Traceback (most recent call last): File "train_and_upload_demo_model.py", line 182, in <module> sys.exit(main()) File "train_and_upload_demo_model.py", line 158, in main config = json.load(configFile) File "C:\Users\Pankaj\AppData\Local\Programs\Python\Python36-32\lib\json\__init__.py", line 299, in load parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw) File "C:\Users\Pankaj\AppData\Local\Programs\Python\Python36-32\lib\json\__init__.py", line 354, in loads return _default_decoder.decode(s) File "C:\Users\Pankaj\AppData\Local\Programs\Python\Python36-32\lib\json\decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Users\Pankaj\AppData\Local\Programs\Python\Python36-32\lib\json\decoder.py", line 355, in raw_decode obj, end = self.scan_once(s, idx) json.decoder.JSONDecodeError: Invalid \escape: line 11 column 34 (char 461) ``` content of config.json file ``` { "host": "localhost", "port": 8983, "collection": "techproducts", "requestHandler": "query", "q": "*:*", "efiParams": "efi.user_query='$USERQUERY'", "userQueriesFile": "user_queries.txt", "trainingFile": "exampleTrainingFile.txt", "trainedModelFile": "exampleTrainedModel.txt", "trainingLibraryLocation": "D:\liblinear-2.11", "trainingLibraryOptions": "-q", "solrFeaturesFile": "exampleFeatures.json", "solrFeatureStoreName": "exampleFeatureStore", "solrModelFile": "exampleModel.json", "solrModelName": "exampleModel" } ``` can i get to know where i am making the mistake? Is this is the error because of "trainingLibraryLocation": "D:\liblinear-2.11", syntax?? because this is the line no. 11 Is there any other way to pass directory location.
