[Bug] IoTDB Gaussian_HMM/GMM_HMM Inference Model Execution Error: Data Type Conversion Exception

### 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

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start at the CALL INFERENCE entry point and InferenceOperator.java:201; reproduce the gaussian_hmm and gmm_hmm queries on IoTDB 2.0.5, focusing on the pandas Interval conversion error shown in the datanode log. Done means both inference calls execute normally without the reported exception.
