Hi, since updating to M1.1 a simple samediff training is giving me an error. Previously it worked without issues. I have a standard multi-lingual cased BERT model which I’m loading into sd with: ```auto SameDiff sd = TFGraphMapper.importGraph(new ByteArrayInputStream(pretrainedModel)); ``` The stacktrace is: ![image](https://canada1.discourse-cdn.com/flex035/uploads/konduit/original/1X/c1eff2a941e6760fe138a433d93a4fd632891743.png) I guess this is related to the latest change documented here [Fixes https://github.com/eclipse/deeplearning4j/issues/8876 by agibsonccc · Pull Request #9357 · eclipse/deeplearning4j · GitHub](https://github.com/eclipse/deeplearning4j/pull/9357). ---

@lln Could you please try the new tensorflow import? That graph mapper was left there for backwards compatibility, but it’s suggested to try the new import. See: > **[Model Import Framework](https://deeplearning4j.konduit.ai/samediff/explanation/model-import-framework)** > > Model import framework overview and examples ---

@agibsonccc Thanks for the reply. I refactored it to use `TensorflowFrameworkImporter` but I’m now getting an error ```auto Caused by: java.io.FileNotFoundException: nd4j-op-def.pbtxt cannot be opened because it does not exist at org.nd4j.common.io.ClassPathResource.getInputStream(ClassPathResource.java:248) at org.nd4j.common.io.ClassPathResource.getInputStream(ClassPathResource.java:235) at org.nd4j.samediff.frameworkimport.tensorflow.opdefs.TensorflowOpDescriptorLoader.nd4jOpList(TensorflowOpDescriptorLoader.kt:55) at org.nd4j.samediff.frameworkimport.tensorflow.opdefs.TensorflowOpDescriptorLoader.(TensorflowOpDescriptorLoader.kt:46) ``` ---

@lln I’ve noticed that recently, for some reason the class path resource isn’t being resolved there. As a work around could you take this folder: > **[deeplearning4j/nd4j/samediff-import/samediff-import-tensorflow/src/main/resource...](https://github.com/eclipse/deeplearning4j/tree/master/nd4j/samediff-import/samediff-import-tensorflow/src/main/resources)** > > master/nd4j/samediff-import/samediff-import-tensorflow/src/main/resources and put it in your src/main/resources and run it again? Thanks! ---

I’m working in the same project with @lln so i’m following up on this… @agibsonccc thanks, that helps but we now have an other issue. I’m using the same model as @lln that worked with the import method of M1: java.lang.IllegalArgumentException: Found invalid output tensor named permuteDims for rule ndarraymapping and mapping process for op transpose and input framework name Transpose with definition being name: “transpose” argDescriptor { name: “dtype” argType: DATA\_TYPE } argDescriptor { name: “outputs” argType: OUTPUT\_TENSOR } argDescriptor { name: “input” argType: INPUT\_TENSOR } argDescriptor { name: “permutationVector” argType: INPUT\_TENSOR argIndex: 1 } argDescriptor { name: “permuteDims” argType: INT64 } ``` at org.nd4j.samediff.frameworkimport.process.AbstractMappingProcess.(AbstractMappingProcess.kt:84) at org.nd4j.samediff.frameworkimport.tensorflow.process.TensorflowMappingProcess.(TensorflowMappingProcess.kt:49) at org.nd4j.samediff.frameworkimport.tensorflow.process.TensorflowMappingProcess.(TensorflowMappingProcess.kt:48) at org.nd4j.samediff.frameworkimport.tensorflow.process.TensorflowMappingProcessLoader.instantiateMappingProcess(TensorflowMappingProcessLoader.kt:45) at org.nd4j.samediff.frameworkimport.process.AbstractMappingProcessLoader.createProcess(AbstractMappingProcessLoader.kt:155) at org.nd4j.samediff.frameworkimport.registry.OpMappingRegistry.loadFromDefinitions(OpMappingRegistry.kt:169) at org.nd4j.samediff.frameworkimport.tensorflow.opdefs.TensorflowOpDescriptorLoader.createOpMappingRegistry(TensorflowOpDescriptorLoader.kt:105) at org.nd4j.samediff.frameworkimport.tensorflow.importer.TensorflowFrameworkImporter.(TensorflowFrameworkImporter.kt:45) ```
