The same error occurs if I adjust the BATCH_SIZE lower for every value less, except, when you get to BATCH_SIZE = 1, it works and the network trains.

I saw the new release and tried the below but I would get the same error, except when I run with BATCH_SIZE = 1 and then it will begin to train fine.

got the same issue with
ai.djl.pytorch:pytorch-native-cu121:2.3.0, ai.djl.pytorch:pytorch-jni:2.3.0-0.28.0 and cuda 12.4.1
rollback to
ai.djl.pytorch:pytorch-native-cu117:1.13.1, ai.djl.pytorch:pytorch-jni:1.13.1-0.28.0 and cuda 11.7.0
fixed the issue

@ebremer you can try to use this tool to identify which dependency it can't find

Some measure of success...
I removed all CUDA libraries I had on my system (there were several) and installed 11.7 only. Everything worked with:

        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-model-zoo</artifactId>
        </dependency>        
        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-engine</artifactId>
        </dependency>
        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-native-cu117</artifactId>
            <classifier>win-x86_64</classifier>
            <version>1.13.1</version>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-jni</artifactId>
            <version>1.13.1-0.28.0</version>
            <scope>runtime</scope>
        </dependency>

I removed 11.7 and installed 12.1 only. I updated the pom to

        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-model-zoo</artifactId>
        </dependency>        
        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-engine</artifactId>
        </dependency>
        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-native-cu121</artifactId>
           <classifier>win-x86_64</classifier>
            <version>2.2.2</version>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>ai.djl.pytorch</groupId>
            <artifactId>pytorch-jni</artifactId>
            <version>2.2.2-0.28.0</version>
            <scope>runtime</scope>
        </dependency>

but it could not find the cuda environment...

Success!
I did some debugging on the DJL code and found out what was happening and not happening.
Tracing through ai.djl.util.cuda.loadLibrary(), the code would find C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common\cudart64_65.dll because CUDA_PATH was not defined, it was defined as CUDA_PATH_v12.1 by the installer. Further, C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.1\bin was not on the PATH. I renamed CUDA_PATH_v12.1 to CUDA_PATH since that is the environmental variable looked for at line 241. At this point, it failed to load because line 253 breaks the path for C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.1\bin\cudart64_12.dll down to just the filename without the path and so it failed to load at line 255. I added C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.1\bin to the PATH variable and it was then able to load the CUDA 12.1 enabling GPU training to finally run.
