Deepspeech training problem: DeepSpeech.py execution gives Illegal instruction (core dumped)

Hello, I am attempting to further train the model (english), however when executing the python DeepSpeech .py --helpfull command in the recommended python venv (to see if training is working) I get the “Illegal instruction (core dumped)” response; actually I get this whenever I attempt to execute the DeepSpeech.py command.
I have read through the documents extensively, and followed the “Training Your Own Model” instructions to the letter, including trying other suggestions from online sources however nothing has solved this problem.
I have downloaded the source (0.9.3) from git and built successfully (using tensorflow 1.15.4 for tflite, and built for TF version 1 as my CPU does not support the AVX instruction set). The actual deepspeech inference application works fine. However, I cannot get past this problem for training on my x86_64 Intel i7 machine. I am running in a VirtualBox environment as detailed below:

Build configuration parameters used:
bazel build --workspace_status_command=“bash native_client/bazel_workspace_status_cmd.sh” --config=monolithic --config=v1 --define=runtime=tflite --local_cpu_resources=4 -c opt --copt=-O3 --copt="-D_GLIBCXX_USE_CXX11_ABI=0" --copt=-fvisibility=hidden //native_client:libdeepspeech.so //native_client:generate_scorer_package

Sorry, no maintenance any more. But this is the same codebase with support at coqui.ai.
