Attribute error : Module "lightgbm" has no attribute "LGBMClassifier" and "Dataset"

I installed lightgbm(2.2.3) using pip version 16.0.0 and got error while uploading the dataset .Code shown below:

import lightgbm as gbm 

d_train=gbm.Dataset(train_x,label=train_y)

File "lightgbm.py", line 13, in
import lightgbm as gbm
File "S:\MP pillai meet\Minor Project\ml-challenge-6-v1\ml-challenge-6\lightgbm.py", line 104, in d_train=gbm.Dataset(train_x,label=train_y)
AttributeError: module 'lightgbm' has no attribute 'Dataset'

File "lightgbm.py", line 13, in, this is the thing, your script file name should not have the same name as the module lightgbm. Change your script file name should solve the problem.

I think this error of attribute Attribute Error in Python, see:

An attribute in Python means some property that is associated with a particular type of object. In other words, the attributes of a given object are the data and abilities that each object type inherently possesses.

Maybe you create a similar python script and is get like the default python module lightgbm.

Try to start developing with start steps, working well for me , see similar examples of errors:

>>> import lightgbm 
>>> from lightgbm import *

This is an error of sintax import (bad ligtgbm):

>>> from ligtgbm import Dataset
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named ligtgbm
>>> from lightgbm import Dataset

Error of non defined:

>>> d_train=lightgbm.Dataset(train_x,label=train_y)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'train_x' is not defined
>>> train_x =''
>>> train_y =''
>>> d_train=lightgbm.Dataset(train_x,label=train_y)
>>> dir(d_train)
