Version Problem?

Open winsway opened this issue 3 years ago • 20 comments

I have installed the CUDA 11.1.1. Then I run the samples, I get the problem :Exception in thread "main" java.lang.UnsatisfiedLinkError: Error while loading native library "JCudaRuntime-11.1.1-windows-x86_64"

It might be. Try changing the version number to 11.1.0 in https://github.com/jcuda/jcuda-samples/blob/master/JCudaSamples/pom.xml#L11 . If this does not help, posting the full error message may be helpful.

When I change the version number jcuda from 11.1.1 to 11.0.0. it can work.

Found 1 devices

But jcusolver can not run. Because , I need to solve sparse matrix. the matrix is very large. I want to use gpu to accelerate calculation speed.

Sorry for the delay here, and sorry for the possibly wrong information: I mentioned 11.1.0, but the actual version number (that also matches the version of CUDA that you have installed) should be 11.1.1. (In fact, 11.1.0 has never been released).

Regarding the error: It should print an additional stack trace, saying "Stack trace from the attempt to load the library as a resource", and this one might contain more helpful information. I guess it will say "Cannot find dependent libraries".

Specifically, you said

When I change the version number jcuda from 11.1.1 to 11.0.0. it can work.

Did you explicitly try it with 11.1.1? This should work when you have installed CUDA 11.1. If it does not work, posting the (complete) stack trace might bring some insights.

I change the pom the dependcy of jcuda to 11.1.1

I just noticed that java.base/ part in the stack traces. There recently has been an issue about JCuda and the Java module system that might be related. I haven't understood/investigated this in all detail, and am not sure whether it would show up as this exact error message/stack trace.

A "back to the roots" test would be (very pragmatic)

  • Create a directory
  • Add https://repo1.maven.org/maven2/org/jcuda/jcuda/11.1.1/jcuda-11.1.1.jar
  • Add https://repo1.maven.org/maven2/org/jcuda/jcuda-natives/11.1.1/jcuda-natives-11.1.1-windows-x86_64.jar
  • Add http://www.jcuda.de/tutorial/JCudaRuntimeTest.java
  • In the directory
    • Run javac -cp ".;jcuda-11.1.1.jar;jcuda-natives-11.1.1-windows-x86_64.jar" JCudaRuntimeTest.java
    • Run java -cp ".;jcuda-11.1.1.jar;jcuda-natives-11.1.1-windows-x86_64.jar" JCudaRuntimeTest

This should print some basic message about a pointer that has been created.

If this does not work, then the issue is almost certainly related to the module system, and I'll have to take another look at that.

Maybe @cfries : Do you know or remember whether the problem for you also showed up as a message that only said "No resource found with name '/lib/JCudaRuntime-11.1.1-windows-x86_64.dll'", without further details?

If this is the case, I'd like to try out the possible (simple) fix that was mentioned, about just changing the call to LibUtils.class.getClassLoader().getResourceAsStream(resourceName);. (I'll have to install a newer Java version for that - I'm badly out of date here...)

OK, that starts to get confusing. How exactly are you starting the JCudaPrintDeviceInfo when you see the execption? I've seen that there is some Maven related output - do you run some magic command from an IDE there? Maybe the classpath/dependency reolution is not working properly. The native library is contained in the jcuda-natives-11.1.1-windows-x86_64.jar, and when the small, standalone test works, it appears to not be related to the Java version in general...

Yeah, I run the command on the VScode, it is easy to use terminal. My Jcuda example was run on the Netbeans.

Dear sir, I found the problem that i depende on my native Jcuda. it make error. now it can work , thanks for your help.

Yeah, I try it again. most examples can be run. There are some libraries without exist. Such as "JCudaDriver-11.1.1-windows-x86_64; JCudnn-11.1.1-windows-x86_64; "

The JCudaDriver-11.1.1-windows-x86_64.dll should be there (together with the Runtime version).

But for JCudnn, you also need the cuDNN binaries (you can download them at https://developer.nvidia.com/cudnn If you are a registered developer)

When I run the class JCudaConstantMemoryExample , it can not work. this is not relate to JCudnn.

The JCudaDriver-11.1.1-windows-x86_64.dll and JCudaRuntime-11.1.1-windows-x86_64.dll are located in the same JAR file. Are you sure that this is not the same error as the first one?

You could try the same procedure as in https://github.com/jcuda/jcuda-samples/issues/10#issuecomment-821852069 , but using

import jcuda.*;
import jcuda.driver.*;
public class JCudaDriverTest
{
    public static void main(String args[])
    {
        JCudaDriver.init(0);
        System.out.println("Done);
    }
}

You could try the same procedure as in #10 (comment) , but using

public class JCudaDriverTest

    public static void main(String args[])
    {
        JCudaDriver.init(0);
        System.out.println("Done);
    }
}

it appears this problem, i can not work.

I don't know the IDE that you are using there, and how it actually issues the Maven commands for building and running the application.

But to be sure:

  • The JCudaPrintDeviceInfo sample does work, but the JCudaDriverTest does not work, is that correct?
  • When you apply the process from https://github.com/jcuda/jcuda-samples/issues/10#issuecomment-821852069 with the JCudaDriverTest (instead of JCudaRuntimeTest), does it work or not?

My IDE is Netbeans that a open source IDE. Now I have run the code. I set the verison number is 11.1.1. Every class can not work besides package jcuda.driver.gl.samples

   <groupId>org.jcuda</groupId>
    <artifactId>jcuda-samples</artifactId>
    <version>0.0.0-SNAPSHOT</version>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <jcuda.jcudaVersion>11.1.1</jcuda.jcudaVersion>
    </properties>

    <name>JCudaSamples</name>
    <description>Samples for JCuda</description>
    <url>http://www.jcuda.org</url>

Then I set verison number to 11.0.0.

  • jcuda.nvrtc.samples package can not work
  • jcuda.jcusolver.samples package can not work
  • jcuda.jcudnn.samples package can not work
  • jcuda.driver.samples package ->JCudaVectorAdd class can not work
  • jcuda.driver.samples package ->JCudaReduction class can not work
  • jcuda.driver.samples package ->JCudaDynamicParallelism class can not work
  • jcuda.driver.samples package ->JCudaDriverStreamCallbacks class can not work
  • jcuda.driver.samples package ->JCudaDriverBasicGraphExample class can not work
  • jcuda.driver.samples package ->JCudaConstantMemoryExample class can not work.

You didn't answer the question of whether it works on the console. What you are saying about "works or doesn't work" (depending on the version and package) is pretty confusing for me right now. Either it works or it doesn't. But generally speaking: If JCuda does not work for you, try https://github.com/bytedeco/javacpp-presets/tree/master/cuda

Maybe you also overlooked the disclaimer in the README: Copy the sample that you want into your IDE, add the JCuda JARs as dependencies, and if there's a problem, then be specific about the problem.

Okay, Thanks for your help. Many thanks~
