### Search before asking - [x] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar. ### Version CentOS Linux release 7.9.2009, IoTDB 2.0.5 ### Describe the bug and provide the minimal reproduce step ```sql IoTDB> show TIMESERIES root.db.sensor.tmp.device_100.** +-------------------------------------------------+-----+-----------+--------+--------+-----------+----+----------+--------+------------------+--------+ | Timeseries|Alias| Database|DataType|Encoding|Compression|Tags|Attributes|Deadband|DeadbandParameters|ViewType| +-------------------------------------------------+-----+-----------+--------+--------+-----------+----+----------+--------+------------------+--------+ | root.db.sensor.tmp.device_100.val| null|root.db| DOUBLE| GORILLA| LZ4|null| null| null| null| BASE| +-------------------------------------------------+-----+-----------+--------+--------+-----------+----+----------+--------+------------------+--------+ ``` ```sql IoTDB> CALL INFERENCE(gaussian_hmm, "select val from root.db.sensor.tmp.device_100.val where time >= now()-2h and time <= now()-1h", generateTime=true) Msg: org.apache.iotdb.jdbc.IoTDBSQLException: 301: Error occurred while executing inference:[Inference model internal error: int() argument must be a string, a bytes-like object or a real number, not 'pandas._libs.interval.Interval'] ``` ```sql IoTDB> CALL INFERENCE(gmm_hmm, "select val from root.db.sensor.tmp.device_100.val where time >= now()-2h and time <= now( )-1h", generateTime=true) Msg: org.apache.iotdb.jdbc.IoTDBSQLException: 301: Error occurred while executing inference:[Inference model internal error: int() argument must be a string, a bytes-like object or a real number, not 'pandas._libs.interval.Interval'] ``` ### What did you expect to see? Can normally call Gaussian_HMM/GMM_HMM machine learning models ### What did you see instead? Can normally call Gaussian_HMM/GMM_HMM machine learning models ### Anything else?
