Pytorch not available for Installing

[GaurDev06]

Hi there, I am working on KMM project and want to implement pytorch in my kmm but getting error

Could not resolve de.voize:pytorch-lite-multiplatform:0.3.3. Required by: project :shared

[Legion2]

The project is published to maven central https://search.maven.org/artifact/de.voize/pytorch-lite-multiplatform/0.3.3/jar. Make sure you include maven central repository in your build config.

[GaurDev06]

Hi, Thanks for following up on this and for your response. I also included the maven like this buildscript { repositories { gradlePluginPortal() google() mavenCentral() } dependencies { classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0") classpath("com.android.tools.build:gradle:7.2.1") } }

allprojects { repositories { google() mavenCentral() } }

tasks.register("clean", Delete::class) { delete(rootProject.buildDir) } Is there anything wrong?

[Legion2]

No this looks right, I created a test project using a basic koltin multiplatform project setup and added your config.

Then I added to app/build.gradle.kts:

kotlin {
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("de.voize:pytorch-lite-multiplatform:0.4.0") // added this
            }
        }
    }
}

And this works fine.

PS: You can better format your code snippets using a ``` code block, see Markdown Syntax

HI @Legion2 I am trying in same way

sourceSets {
        val commonMain by getting{
            dependencies {
                implementation("com.soywiz.korlibs.korim:korim:$korimVersion")
                implementation("org.jetbrains.kotlin:kotlin-stdlib-common")
                implementation( "org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutineVersion")
                implementation("de.voize:pytorch-lite-multiplatform:0.4.0")

            }
        }

But its showing error Could not resolve de.voize:pytorch-lite-multiplatform:0.4.0.

[Legion2]

@GaurDev06 can you share your complete project (is is open source on github), so we can reproduce the problem?

[GaurDev06]

@Legion2
please find the with the help of given link. https://github.com/GaurDev06/ApplicationDemo.git Thanks

[Legion2]

I have checked out your project and can run ./gradlew build and ./gradlew installDebug on my linux without problems. Which command results in the error?

[GaurDev06]

When I am running this project on my mac then I will get the error and it says that:- Could not resolve de.voize:pytorch-lite-multiplatform:0.3.3. Required by: project : shared

[Legion2]

I will test on a mac next week.

[GaurDev06]

@Legion2 Thank for the update. And waiting for your response. TIA

@GaurDev06

With your repo I get the following error on a M1 MacBook Pro on ./gradlew build.

This is because a blank Kotlin Multiplatform Project includes a iosSimulatorArm64 target that is currently not support by this library. If you remove the target it works fine.

@erksch we should add the iosSimulatorArm64() target, we just need to add it to gradle with iosSimulatorArm64Main.dependsOn(iosMain) and publish I think

[GaurDev06]

Hi @erksch Thanks for the Update and your time but when we install it without the iosSimulatorArm64() and iosSimulatorArmX64 then we are not able to run the application in the xcode it's showing error like Undefined symbols for architecture x86_64: "_OBJCCLASS$_TorchModule", referenced from: objc-class-ref in shared(result.o) objc-class-ref in shared(result.o) "_OBJCCLASS$_Tensor", referenced from: objc-class-ref in shared(result.o) objc-class-ref in shared(result.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) So if there any other way then please let us know. thanks again for your efforts.

You seem to not have included the PLMLibTorchWrapper pod correctly. Please check out the updated README.

And also disabled the bitcode in xcode. Please correct me Thanks

[erksch]

remove the iosSimulatorArm64() target

[GaurDev06]

Hi @erksch, Thanks for your response, I have removed the iosSimulatorArm64() from gradle and successfullly build the kmm gradle but in IOS Xcode getting the below error

[erksch]

Your iosApp/Podfile seems broken to me:

//use_frameworks!

is not a valid way to comment out a line in Ruby, instead use:

# use_frameworks!

[GaurDev06]

Hi @erksch Thanks for your fast response , I used the same "# use_frameworks!" but for commenting here i used that because it will show you the heading when i will post it

[erksch]

Ok. Your XCode project does not link the PLMLibTorchWrapper pod.

Please send me the content of shared/shared.podspec and the output of ls iosApp/Pods.

Looks good to me. Please provide a reproducible example so we can debug or take a look at our new example project for reference.

Hi @erksch, Please find the file for your reference https://github.com/GaurDev06/DemoApp.git

@GaurDev06 thanks, I checked out your repo. First thing, iosApp/Pods should be in your .gitignore, the folder is autogenerated.

Regarding your issue, please try to delete the iosApp/Pods folder, run cd iosApp && pod install and try to build the app again.

@GaurDev06 have you been able to resolve your issue? If so, I'd close this issue
