How to Fix: Tensorflow on Arm with "No session factory registered" Error
Tensorflow on Arm error fix
📋 Table of Contents
The 'No session factory registered' error occurs when TensorFlow is unable to find a valid session factory, which is necessary for creating and managing sessions. This error affects users who have successfully compiled TensorFlow on their Arm target but encounter issues when running their code.
This error can be frustrating because it prevents the user from utilizing TensorFlow's session management features, making it difficult to reproduce and debug models. To resolve this issue, we will explore two primary methods for fixing the 'No session factory registered' error.
⚠️ Common Causes
- The first main reason why this error happens is due to a mismatch between the host system and the target system's TensorFlow configuration. The `bazel-out` directory generated by TensorFlow-on-Arm contains Arm-specific configurations, which may not be compatible with the host system's Linux environment.
- An alternative reason for this error could be that the `libtensorflow.so` and `libtensorflow_frame.so` libraries were not correctly linked during the compilation process. This can occur if the linker flags are incorrect or if the library paths are not properly set.
🔧 Proven Troubleshooting Steps
Update TensorFlow configuration to match host system
- Step 1: Step 1: Modify the `bazel-out/armeabi-opt/genfiles` directory to use a compatible TensorFlow configuration. This can be done by updating the `tensorflow.bzl` file to use Linux-specific flags and configurations.
- Step 2: Step 2: Rebuild the TensorFlow package using the modified configuration. This will ensure that the resulting libraries are compatible with the host system's Linux environment.
- Step 3: Step 3: Verify that the updated libraries are correctly linked during the compilation process.
Verify library links and paths
- Step 1: Step 1: Inspect the linker flags used during the compilation process to ensure they are correct. Make sure to include the necessary `-L` flags to specify the library paths.
- Step 2: Step 2: Verify that the `libtensorflow.so` and `libtensorflow_frame.so` libraries are correctly linked during the compilation process. This can be done by checking the resulting binary's dependencies and ensuring that all required libraries are present.
✨ Wrapping Up
To resolve the 'No session factory registered' error, it is recommended to update TensorFlow configuration to match the host system's Linux environment or verify library links and paths. By following these steps, users can ensure that their Arm target is correctly configured for TensorFlow usage.
