【python】lightgbm 无法打开文件

问题：文件无法打开

在使用 lightgbm 读取模型文件时不能打开

报错：

Traceback (most recent call last):
  File "detect_interpretability_.py", line 176, in <module>
    lightgbm_test(White_data, os.path.basename(data_path), model_file = model_file, interpretability_path = interpretability_path, label = int(detection_label))
  File "detect_interpretability_.py", line 54, in lightgbm_test
    gbm = lgb.Booster(model_file = model_file) 
  File "/opt/work/nta/venv/lib/python3.6/site-packages/lightgbm/basic.py", line 2642, in __init__
    ctypes.byref(self.handle)))
  File "/opt/work/nta/venv/lib/python3.6/site-packages/lightgbm/basic.py", line 125, in _safe_call
    raise LightGBMError(_LIB.LGBM_GetLastError().decode('utf-8'))
lightgbm.basic.LightGBMError: Could not open model.model

解决：换成绝对路径

笑哭了都

MODEL_FILE = '/home/root/litianchao/model.model'
