问题 I just installed tensorflow using the instructions for the virtualenv method. The installation process went smoothly, so I don't think there was any problem there. After installation I proceeded to try and import it to validate that everything is ok, and I got the following message: [1] 4492 illegal hardware instruction (core dumped) python This happened after I use the following command using th python interactive console: import tensorflow as tf I tried using the link with pip to reinstall

问题 I am currently trying to shoot photos within an app with the UIImagePickerController, saving it to the local database and upload them later to a service. But it seems that the metadata (especially EXIF) are not bundled with this image automatically. I've tried to extract it like this: func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { self.imageDelegate?.saveImage( image: info[UIImagePickerControllerOriginalImage] as! UIImage,

问题 I'm using the DataOutputStream#WriteLong method in the java programming language to write a long to a stream, and I need to be able to read it from C# using the BinaryReader class from C# to try to read the data, the BinaryReader is connected to a NetworkStream that uses the TcpClient socket. The java DataInputStream#ReadLong method is used to read the long value sent from the DataOutputStream in Java, however I'm trying to use the BinaryReader class to read this value. Here's the method I

问题 This is my code: int i = 5; const int * cpi = &i; //pointer to const int * pi = cpi; //Error: a value of type "const int*" cannot be assigned to an entity of type "int*" 回答1: i is mutable, cause it is not a const type. You try to store a int address in a const int address via cpi . To solve it you have to actually hand over the values not the addresses. 来源： https://stackoverflow.com/questions/34542470/why-this-error-a-value-of-type-const-int-cannot-be-assigned-to-an-entity-of

问题 Based on this this question: How to read a binary file into a vector of unsigned chars In the answer they have: std::vector<BYTE> readFile(const char* filename) { // open the file: std::basic_ifstream<BYTE> file(filename, std::ios::binary); // read the data: return std::vector<BYTE>((std::istreambuf_iterator<BYTE>(file)), std::istreambuf_iterator<BYTE>()); } Which reads the entire file into the vector. What I want to do is read (for example) 100 bytes at a time in the vector, then do stuff,

问题 When I create a new window using .Show() , it shows the new window, however my icons are grouped like below: I don't want that. I want the icons to be separate because I want my users to easily open the window that they want instead of having to click it, view the list of open windows, then choosing which one they want every time. I don't want to use .ShowDialog() because I need the users to be able to focus on either window no matter the state of the other. Meaning, both windows will need to
