我使用scikit_learn.GridSearchCV为我的Keras神经网络网格搜索超参数(用于回归问题)。我的神经网络的输出是一个实值: #generate a model (createModel is a function which returns a keras.Sequential model)
model = keras.wrappers.scikit_learn.KerasRegressor(build_fn=createModel)
#run the GridSearch
paramGrid = dict( epochs=[100, 250, 500], batch
我正在读有关列转换器的scikitlearn教程。给定的示(https://scikit-learn.org/stable/modules/generated/sklearn.compose.make_column_selector.html#sklearn.compose.make_column_selector)工作,但当我尝试只选择几列时,它给出了错误。 MWE import numpy as np
import pandas as pd
import seaborn as sns
from sklearn.compose import make_column_transformer
这些天我正在学习keras,在使用scikit时遇到了一个错误--学习API.Here可能是有用的:
环境:
python:3.5.2
keras:1.0.5
scikit-learn:0.17.1
码
import pandas as pd
from keras.layers import Input, Dense
from keras.models import Model
from keras.models import Sequential
from keras.wrappers.scikit_learn import KerasRegressor
from sklearn.c
我正在尝试安装scikit-使用docker image学习!它失败了,下面是错误:
ImportError: Numerical Python (NumPy) is not installed. scikit-learn requires NumPy >= 1.8.2. Installation instructions are available on the scikit-learn website: http://scikit-learn.org/stable/install.html Failed building wheel for scikit-learn
但是在日
当部署到弹性豆茎时,我一直会得到错误:
Partial import of sklearn during the build process.

从google的结果来看,整个国际社会似乎从来没有遇到过这个php错误:
我正在尝试设置Typo3 CMS并且我得到了这个错误
Type of TYPO3\CMS\Core\IO\CsvStreamFilter::$params must be mixed (as in class php_user_filter) in C:\xampp\htdocs\typo3test\example-project-directory\public\typo3\sysext\core\Classes\IO\CsvStreamFilter.php on line 26
该文件的第26行如下所示:

我正在学习python scikit。此处给出的示例显示了每个集群中出现次数最多的单词,而不是集群名称。
我发现km对象有"km.label“,它列出了质心id,也就是数字。
我有两个问题
1. How do I generate the cluster labels?
2. How to identify the members of the clusters for further processing.
我有k-means的工作知识,并了解tf-ids的概念。
这是关于TF 2.0的。 请在下面找到我的代码,它使用sklearn.model_selection.GridSearchCV对mnist数据集执行GridSearch和交叉验证,工作得很好。 # Build Function to create model, required by KerasClassifier
def create_model(optimizer_val='RMSprop',hidden_layer_size=16,activation_fn='relu',dropout_rate=0.1,regularization_fn=t
