Hy家伙我想要我textView有这个字体:"Apple SD Gothic Light"...我在这里使用此代码属于:
if (titolo.text == NSLocalizedString("SEVENTH_ANNOTATION_TITLE", comment: "")){
// aggiungo le immagini all'array
pageImages = [UIImage(named: "TeatroMassimoBellini1.png")!,
UIImage(named: "TeatroMassimoBellini2.png")!,
UIImage(named: "TeatroMassimoBellini3.png")!]
textFieldDescrizione.text = NSLocalizedString("SEVENTH_ANNOTATION_DESCRIPTION", comment: "")
textFieldDescrizione.font = UIFont.preferredFontForTextStyle("AppleSDGothicNeo-Light")
textFieldDescrizione.textAlignment = NSTextAlignment.Justified
}
但它不起作用....你能帮助我吗？对不起我的英语不好!:)
我对这个问题的标题有同样的问题：
操作无法完成。（kCLErrorDomain 错误 1。）
此错误是当用户按下不允许本地化访问权限时。这是我的代码：
@IBAction func getLocation(sender: UIButton)
{
// i servizi di localizzazione sono abilitati?
if (CLLocationManager.locationServicesEnabled())
{
// abbiamo l'autorizzazione ad accedere ai servizi di localizzazione?
switch CLLocationManager.authorizationStatus(){
case .Denied:
// NO
displayAlertWithTitle("Denied", message: "Location services are not allowed for this app")
case .NotDetermined:
// NON SAPPIAMO, DOBBIAMO CHIEDERE
self.locationManager = CLLocationManager()
if (locationManager != nil)
{
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
}
case .Restricted:
// SONO STATE APPLICATE DELLE RESTRIZIONI, NON ABBIAMO ACCESSO …如何在 mapview 中为 CLLocation 数组创建路线？我创建了一条折线，我想通过步行创建一条路线。这是我的代码：
@IBAction func addPolyline(sender: AnyObject) {
let locations = [CLLocation(latitude: annotazioni.objectAtIndex(0).coordinate.latitude, longitude:annotazioni.objectAtIndex(0).coordinate.longitude ),
CLLocation(latitude: annotazioni.objectAtIndex(1).coordinate.latitude, longitude:annotazioni.objectAtIndex(1).coordinate.longitude ),
CLLocation(latitude: annotazioni.objectAtIndex(2).coordinate.latitude, longitude:annotazioni.objectAtIndex(2).coordinate.longitude ),
CLLocation(latitude: annotazioni.objectAtIndex(3).coordinate.latitude, longitude:annotazioni.objectAtIndex(3).coordinate.longitude ),
CLLocation(latitude: annotazioni.objectAtIndex(4).coordinate.latitude, longitude:annotazioni.objectAtIndex(4).coordinate.longitude ),
CLLocation(latitude: annotazioni.objectAtIndex(5).coordinate.latitude, longitude:annotazioni.objectAtIndex(5).coordinate.longitude ),
CLLocation(latitude: annotazioni.objectAtIndex(6).coordinate.latitude, longitude:annotazioni.objectAtIndex(6).coordinate.longitude )]
addPolyLineToMap(locations)
}
func addPolyLineToMap(locations: [CLLocation!]){
var coordinates = locations.map({ (location: CLLocation!) -> CLLocationCoordinate2D in
return location.coordinate
})
let geodesic = MKGeodesicPolyline(coordinates: &coordinates, count: locations.count)
mapView.addOverlay(geodesic)
}
func mapView(mapView: MKMapView!, viewForOverlay overlay: MKOverlay!) -> MKOverlayRenderer! {
if (overlay is MKPolyline) …大家好，我想提取预训练 resnet50 的全连接层的 in_features。
我之前创建了一个为我提供特征向量的方法：
def get_vector(image):
#layer = model._modules.get('fc')
layer = model.fc
my_embedding = torch.zeros(2048) #2048 is the in_features of FC , output of avgpool
def copy_data(m, i, o):
my_embedding.copy_(o.data)
h = layer.register_forward_hook(copy_data)
tmp = model(image)
h.remove()
# return the vector
return my_embedding
我在这里调用这个方法之后：
column = ["FlickrID", "Features"]
path = "./train_dataset/train_imgs/"
pathCSV = "./train_dataset/features/img_info_TRAIN.csv"
f_id=[]
features_extr=[]
df = pd.DataFrame(columns=column)
tr=transforms.Compose([transforms.Resize(256),
transforms.CenterCrop(224),
transforms.ToTensor(),
transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])])
test = Dataset(path, pathCSV, transform=tr)
test_loader = DataLoader(test, batch_size=1, num_workers=2, shuffle …
