with open('wrangler_new.pkl','rb') as fp:
    wrangler = pickle.load(fp)
float_scaler_mean = wrangler['float_scaler_mean']
float_scaler_std = wrangler['float_scaler_std']

float_feature_names = wrangler['float_feature_names']
ohe_fields = wrangler['ohe_fields']
feature_names = wrangler['feature_names']

booster = xgboost.Booster()
booster.load_model('new_0001.model')

这就是错误
