CheXNet-master: CUDA out of memery [How to Solve]

add with torch.no_grad() before for i, (inp, target) in enumerate(test_loader): no error will be reported

with torch.no_grad():
    for i, (inp, target) in enumerate(test_loader):
        target = target.cuda()
        gt = torch.cat((gt, target), 0)
        bs, n_crops, c, h, w = inp.size()
        input_var = torch.autograd.Variable(inp.view(-1, c, h, w).cuda())
        output = model(input_var)
        output_mean = output.view(bs, n_crops, -1).mean(1)
        pred = torch.cat((pred, output_mean.data), 0)

[Solved] AttributeError: module ‘tensorflow‘ has no attribute ‘distributions‘

Recently, I was watching Mo fan’s PPO code running problems

norm_dist = tf.distributions.Normal(loc=mu, scale=sigma)

report errors:

AttributeError: module 'tensorflow' has no attribute 'distributions'

TF. Distributions is one of the core components provided by tensorflow. It is used to implement some common probability distributions and gives a series of auxiliary calculation functions.

The reason for the problem:
I didn’t look carefully. Mo fan’s version of TensorFlow is TensorFlow r1.3
his version is too old. It’s better to upgrade 1.2.0 to the same version
pay attention to the version of the code in the future

[Solved] Timeout failure when upgrading horizon DAAS from 9.0.1/20.2.0 to 9.1.0/21.1.0

Problem Description
When we upgrade from VMware Horizon DaaS 9.0.1/20.2.0 to Horizon Daas 9.1.0/21.1.0, an error is reported on the HAL side and the upgrade fails with an error similar to the following in the HAL’s /var/log/horizon-air-link.log log.

Cause.
The issue is caused by a timeout due to a high load on vCenter Server during deployment causing the SP1 appliance to take longer to reboot. This is a known issue with 9.0.1/20.2.0 upgrades to 9.1.0/21.1.0 for which there is no official VMware solution.
Temporary treatment.
Please check to make sure that the vCenter instance and vCenter cluster cluster load at the location where the SP is part of is not under tension before trying to schedule the deployment task again.

[Solved] Circular view path [index]: would dispatch back to the current handler URL [] again. Che

Error report content
circular view path [index]: would dispatch back to the current handler URL// login/index] again. Check your viewresolver setup（ Hint: This may be the result of an unspecified view, due to default view name generation.)

Change @ controller to @ restcontroller

The @restcontroller annotation is equivalent to the function of @ResponseBody + @ controller
without annotation, @ResponseBody or @restcontroller will set the return value to JSON format, otherwise it will automatically think that you are returning a page
in the @ controller annotation, you can return a string or a template name that matches the string, that is, directly render the view and use it with HTML pages,

In this case, the front-end and back-end requirements are relatively high. The Java back-end code should be rendered in combination with HTML. The data of the model object (or modelandview) will be used to fill in the relevant attributes in the user view, and then displayed to the browser. This process can also be called rendering

In @restcontroller, you should return an object, that is, return a user object. At this time, you can also see that the return is a JSON string corresponding to a user object without a page. The function of the front end is to use the returned JSON to parse and render the page, and the code of the Java back end is relatively free.

Method to solve uncaught typeerror: cannot set property ‘onclick’ of null error

Problem analysis: this error occurs when the JS file is placed in the head tag and the onclick event is bound

reason:

W3school introduces that the browser loads the button node before executing JS. When the browser parses from top to bottom, the button node bound to onclick cannot be found

For example:

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Events</title> 
<script>
    var Btn = document.getElementById('btn');
    Btn.onclick = function(){    
        console.log("push the button ");        
    }
</script> 
</head> 
<body> 
   <button id="btn">Calculation</button> 
</body>
</html>

This error will appear, as shown in the following figure:

Solution 1: use the JS content in window ο nl ο Ad = function () {} wrap it up

<!DOCTYPE HTML>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Events</title>
    <script>
        window.onload = function () {
            var Btn = document.getElementById('btn');
            Btn.onclick = function () {
                console.log("push the button ");
            }
        }
    </script>
</head>
<body>
    <button id="btn">Calculation</button>
</body>
</html>

Solution 2: load the JS file at the bottom

<!DOCTYPE HTML>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Events</title>
</head>
<body>
    <button id="btn">Calculation</button>
    <script>
        var Btn = document.getElementById('btn');
        Btn.onclick = function () {
            console.log("push the button ");
        }
    </script>
</body>
</html>

2、 Solutions

There are many versions on the Internet,

1. Reduce JDK version, such as using java 11, change to Java 8

2. Add the following method to the startup class. Call this method when starting springboot to test the effectiveness of JDK 11

public static void disableWarning() {
    try {
      Field theUnsafe = Unsafe.class.getDeclaredField("theUnsafe");
      theUnsafe.setAccessible(true);
      Unsafe u = (Unsafe) theUnsafe.get(null);

      Class cls = Class.forName("jdk.internal.module.IllegalAccessLogger");
      Field logger = cls.getDeclaredField("logger");
      u.putObjectVolatile(cls, u.staticFieldOffset(logger), null);
    } catch (Exception e) {
      // ignore
    }
  }

  public static void main(String[] args) {
    disableWarning();
    SpringApplication.run(CpmApiApplication.class, args);

ERROR:
ORA-00020: maximum number of processes (150) exceeded
Method 1: Change the processes parameter
To solve the ORA-00020 error, you can increase the parameter value of processes, but you need to start the database normally and log in successfully before you can modify it.
1. Firstly, log in the database successfully by adding the parameter “-prelim”.
