我需要在Excel中使用来自localhost中的Postgres数据库的数据创建一个非常简单的表.
我已经设法使用OpenLink PostgreSQL Lite驱动程序,但看起来不友好或易于管理.我以前在Windows上使用ODBC,但我不确定OS X.我需要它是开源的.
我知道如何使用txt文件编写,numpy.savetxt()但我无法使用整数编写文件.我有以下代码:
new_picks = new_picks.astype(int)
np.savetxt(fname='newPicksData.txt', X=new_picks.astype(int))
这就是我得到的矩阵的样子:

我正在寻找的是这样的:

43 …我想跟踪用户之前的页面而不是当前页面.我试图使用,$ionicHistory.viewHistory()但我可以设法得到它.我是angularjs和$ ionic的新手,所以我想这是一个新手问题.
整个过程的目的是使用Piwik对单页Web应用程序进行漏斗分析,但由于它没有合适的漏斗插件(感谢Piwik),我必须自己实现它.因此,如果您对该主题有任何建议,那么很高兴收到您的来信.
我正在使用ImageDataGenerator和flow_from_directory生成我的数据，并使用model.fit_generator来拟合数据。
默认情况下，仅输出训练数据集的准确性。似乎没有选择将验证准确性输出到终端。
这是我的代码的相关部分：
#train data generator
print('Starting Preprocessing')
train_datagen = ImageDataGenerator(preprocessing_function = preprocess)
train_generator = train_datagen.flow_from_directory(
train_data_dir,
target_size = (img_height, img_width),
batch_size = batch_size,
class_mode = 'categorical') #class_mode = 'categorical'
#same for validation
val_datagen = ImageDataGenerator(preprocessing_function = preprocess)
validation_generator = val_datagen.flow_from_directory(
validation_data_dir,
target_size = (img_height, img_width),
batch_size=batch_size,
class_mode='categorical')
########################Model Creation###################################
#create the base pre-trained model
print('Finished Preprocessing, starting model creating \n')
base_model = InceptionV3(weights='imagenet', include_top=False)
x = base_model.output
x = GlobalAveragePooling2D()(x)
x = Dense(1024, …我有一个对象列表,这些对象是我的代码中的特定类,如此,
[object1, object2, object3, object4, object5, object6]
即该类有两个属性:class.score和class.id
我可能有相同ID的对象.例如.:
[object1.id, object2.id, object3.id, object4.id, object5.id, object6.id] = [1, 2, 3, 4, 2, 3]
但得分不同.例如.:
[object1.score, object2.score, object3.score, object4.score, object5.score,
object6.score] = [0.25, 0.55, 0.6, 0.4, 0.30, .33]
我想要做的是让列表没有这个对象的重复,但是添加了分数.所以对于前面的例子,输出将是:
[object1.id, object2.id, object3.id, object4.id] = [1, 2, 3, 4]
[object1.score, object2.score, object3.score, object4.score] = [.25, .85, .93, .4]
我设法用两个for循环来做到这一点:
k = 1
for object in list_of_objects:
j = 1
for object2 in list_of_objects:
if object.id == object2.id and j > …
