RuntimeError: Input type (torch.FloatTensor) and weight type (torch.cuda.FloatTensor) should be the same
This problem occurs because the tensor of the input model is loaded in the CPU, while the model is loaded on CUDA.
Solution: load the input tensor into CUDA or load the model into CPU
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)
img = img.to(device)
output = model(img)
Or:
model = model.cuda()
img = img.cuda()

Open the debug button to see if the build suite has been modified or not
You need to ensure that the build kit is x86 or x64 relative to OpenCV

the OS X application cannot access the network request. After timeout, an error is reported: http load failed, 0/0 bytes (error code: – 1003 [10: – 72000])
Reason:
sandbox configuration error
Solution:
first confirm whether the HTTPS access policy is enabled for the project, then find the “. Entitlements” file generated by default, and set the app sandbox value to false. Of course, apple stipulates that the sandbox policy must be enabled for the app store on the shelf, so it can target – & gt; Signing& Find the options in capabilities as shown in the figure below and enable them

Recently, during SSM integration, I encountered a bug of classnotfoundexception, which means that the result type corresponding to the return value cannot be found. Finally, I found that I wrote the type and ID inversely.
In addition, if the returned value is a basic data type, use resulttype. If it matches resultmap
, such as collection, map, etc., use resultmap. When facing Baidu debug, you will report similar errors when you see this situation

Running a python flash project on a new machine causes the following problems:
error: while importing 'run_ app_ dev', an ImportError was raised.
resolvent
It is said on the Internet that it is a circular call problem, but this project can run on my laptop. I doubt whether it is the version of flash, because I directly installed the latest Flash. After uninstalling the latest flash, I installed 1.1.2 flash. This problem is solved
Reason: it is mainly because the JDK version is inconsistent
1. The compiled version does not match. 2. The current project JDK version does not support
1. First, view the JDK of the project
File -> Project Structure-> Project Settings -> Project
1.8 must correspond to 8
Check whether the JDK of the current project (module) is the same as that of the project
2. Maven is used in the idea to build the project. The target bytecode version is automatically changed to 1.5 Because no JDK is specified in maven, it will be scanned as the default JDK version View and set the java compiler version (target bytecode version)
File–> Setting–> Build,Execution,Deployment–>Compiler–> Java compiler sets the corresponding module
The appropriate version of target bytecode version, such as JDK1.8 Change 1.5 above to 1.8
Solution:
Add Maven compiler plugin to pom.xml so that it will not automatically become 1.5
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
<encoding>UTF-8</encoding>
