json读取错误json.decoder.JSONDecodeError：无效\ escape

我正在编写一个代码，使用“config.json”文件设置在solr上载模型（train_and_upload_demo_model.py）。但我得到以下错误：json读取错误json.decoder.JSONDecodeError：无效 escape

json.decoder.JSONDecodeError：无效\逃生：行11列34（461焦）这是这里的回溯：

D:\solr640\contrib\ltr\example>python train_and_upload_demo_model.py -c config.json

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" 
    }

我可以让知道我在哪儿我犯了错误？

这是错误，因为“trainingLibraryLocation”：“D：\ liblinear-2.11”，语法？因为这是行号。 11

是否有任何其他方式来传递目录位置。

因此，您可以通过将该字符串替换为不带“D：\”的版本来查明您的问题，然后再次执行您的代码。 –

\l在"trainingLibraryLocation": "D:\liblinear-2.11"被视为转义序列。尝试逃避斜线本身，即。 "D:\\liblinear-2.11"。
