[Solved] RuntimeError: CUDA error: invalid device ordinal

Error Message:
RuntimeError: CUDA error: invalid device ordinal

Solution:

args.device = torch.device('cuda:' + str(args.gpu_id))

Used the gpu_id exceeds that of the GPU card

My code is written in the above way. Different codes are written in different ways. In the final analysis, just change the number after CUDA: to be appropriate

Error received: error: xhr’get’to URL cross domain [How to Solve]

1. Problems encountered

There was a problem when the browser made a request to access another path:

Error received: Error: XHR 'GET' to URL 'https://widevine.eurofins-digitaltesting.com/cert-required/api/Ik0wR1ZCRUNDTkYi.YRMy4w.kgjp1ExZh2r1lcQezAm5HAfZq3J8vXQTBW-Bhdq-K5Y/cert-details'returned status HTTP 0

Knowledge points: for communication between different domains, when encountering complex requests, the client will not send the real request header first, but send the view request to check whether the two sides can communicate. If the verification is successful, send the real request, and the two sides shake hands three times to establish a connection before communication. Therefore, the server and the client have two connections. The first connection is authentication, and the second connection is to send a request to start communication.

Analysis 1: the return value 0 does not exist in the HTTP status code. The reason for the occurrence of HTTP 0 may indicate that the response is empty (or even there is no return header). Means that the connection has been accepted and then closed normally (TCP fin)

Preliminary conclusion: when sending the view request for the first time, the verification fails and returns 0.

① The reason for the verification failure may be that the client does not have a certificate, resulting in no permission to communicate;

② Possibly CORS, unable to communicate between different domains.

Verification ① 1: report bug #3724 in a3sa defect management system and obtain the certificate required for the test. Convert the certificate into the format required by the TV through OpenSSL and build it into the corresponding directory. The test still fails and the verification fails

Verification ① II: the certificate may be used incorrectly. You may need a built-in certificate to enable the browser to parse the request and conduct two-way verification of the certificate. Certificate two-way verification. If anyone is interested, you can comment and sort it out in my post blog

Verification ②: after compiling the built-in certificate, the test still fails. Viewing the log is indeed a CORS problem.

2. Solution

Add a header to the server-side configuration file:

"Access-Control-Allow-Origin"=>"xxxxx Your Link"，

"Access-Control-Allow-Credentials"=>"true"

Error running ‘Android Debugger (-1)‘ [How to Solve]

The Android studio attach debugger suddenly fails. Read the event log and report an error

2: 10 PM can’t bind to local – 1 for debugger

2: 10 PM error running ‘Android debugger (- 1)’: unknown error

2: 10 PM error running ‘Android debugger (- 1)’
invalid argument: argument invalid
[port]

There are similar port occupancy and other errors on the Internet, but those are basically a specific port, which is directly – 1 port. At first, I wanted to change the debugger’s port in preference to use existing manually managed server, and specify a port, so I couldn’t connect directly.

After that, I thought it was because preview and the official version were installed at the same time, and then I reinstalled Android studio.

Finally, it was solved. It turned out that the host file needs to map localhost to 127.0.0.1

127.0.0.1       localhost

PIKA trouble02 — (error) ERR Syntax error, try CLIENT (LIST [order by [addr|idle]| KILL ip:port)

Problem description

Redis was originally used, but now Pika is used. Springboot version 2.1.8 is used. ClientName is configured inside. There is no problem when starting, but the following exception information will be reported when using:

org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool] with root cause

redis.clients.jedis.exceptions.JedisDataException: ERR Syntax error, try CLIENT (LIST [order by [addr|idle]| KILL ip:port)

    @Bean
    public RedisConnectionFactory connectionFactory(RedisProperties redisProperties) {

        JedisClientConfiguration clientConfig = JedisClientConfiguration.builder()
                .clientName("zcx")
                .usePooling().poolConfig(getGenericObjectJedisPoolConfig(redisProperties)).and().readTimeout(redisProperties.getTimeout())
                .build();

        RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration(redisProperties.getHost());
        configuration.setPort(redisProperties.getPort());
        configuration.setPassword(RedisPassword.of(redisProperties.getPassword()));

        return new JedisConnectionFactory(configuration, clientConfig);
    }

2. Solution

After searching, it is caused by the ClientName field. Just remove the ClientName configuration. The problem is found as follows:

Call creation connection in class GenericObjectPool

private PooledObject<T> create() throws Exception {
        ...

        final PooledObject<T> p;
        try {
            p = factory.makeObject();
        } catch (final Throwable e) {
            createCount.decrementAndGet();
            throw e;
        } finally {
            synchronized (makeObjectCountLock) {
                makeObjectCount--;
                makeObjectCountLock.notifyAll();
            }
        }
}

The client setname “zcx” command is called in the JedisFactory class, and an exception is thrown.

@Override
  public PooledObject<Jedis> makeObject() throws Exception {
    final HostAndPort hostAndPort = this.hostAndPort.get();
    final Jedis jedis = new Jedis(hostAndPort.getHost(), hostAndPort.getPort(), connectionTimeout,
        soTimeout, ssl, sslSocketFactory, sslParameters, hostnameVerifier);

    try {
      jedis.connect();
      if (password != null) {
        jedis.auth(password);
      }
      if (database != 0) {
        jedis.select(database);
      }
      if (clientName != null) {
        jedis.clientSetname(clientName);
      }
    } catch (JedisException je) {
      jedis.close();
      throw je;
    }

In the final analysis, pika does not support the client setname command, so when creating a connection, it cannot obtain the connection and report that the command is not supported

error: resource android:attr/lStar not found [Pefect Solution]

Today, the following errors suddenly appear in the project, and the compilation will report an error

D:\AndroidProjects\XXXXX\app\build\intermediates\incremental\mergeDebugResources\
merged.dir\values\values.xml:10858: AAPT: error: resource android:attr/lStar not found.

No one submitted the code. I could still run yesterday, but I suddenly couldn’t do it today. Then there were all kinds of tosses. I tried the common methods for difficult and miscellaneous problems in the development process. Clean project, clear the studio cache and restart, restart the computer, etc. the problems still exist. I searched for a circle and didn’t find the corresponding solutions.

Problem:

The project or third-party library relies on androidx.core: core KTX: + , and there is no limited version. Therefore, the latest core KTX version 1.7.0 is used, and the above compilation error is reported, and it is still sudden.

Solution:

The specific version number depends on the project, not necessarily 1.3.2. I understand that it can be lower than 1.7.0

Method 1: project reference and directly set the specific version number. For example, my project:
implementation "Android. Core: core KTX: 1.3.2"
method 2: the version number is not set in the third-party dependency library. You can add the following code in build.gradle of APP module:
at the same level as Android {}

configurations.all {
    resolutionStrategy {
        force 'androidx.core:core-ktx:1.3.2'
    }
}

Note: the specific version number of remote dependency must be set. Never use the + end. This compilation will pull the corresponding latest remote dependency. Maybe there will be an inexplicable problem that day.

error: resource android:attr/lStar not found [How to Solve]

error: resource android:attr/lStar not found…….

After searching for a long time, there is nothing related to LSTAR under my attr directory. The project has not added LSTAR related fields from the beginning to the end, but the project inexplicably reported this error, that is, it can’t run. It can run in the first minute. Suddenly it can’t run. Do you say it’s annoying or not

To get down to business, the reason is that Android.
