research segmentation fault

when type ./view_generative_model.py ./outputs/steering_model/steering_angle.json or (tensorflow) root@dl126:/data/zeng/research-master# ./train_generative_model.py Using TensorFlow backend. I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcublas.so locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcudnn.so locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcufft.so locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcuda.so locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcurand.so locally Segmentation fault (core dumped)

i get this: Segmentation fault (core dumped)

can anyone explain how to run the code? thx

this is a TF problem, what is your GPU memory?

I also have the same problem while trying to run selfsteering.md. Here is my error log.

not sure if that will be enough… maybe a single model needs to fit entirely in a GPU. I only tested this with TitanX and 1080

in the view steering model.py file I found his error (ValueError: bad marshal data (unknown type code)) result when trying to execute the view steering model.py here is the result from the cmd prompt

Traceback (most recent call last): File "C:\Users\lenovo\Anaconda3\lib\site-packages\keras\utils\generic_utils.py ", line 229, in func_load raw_code = codecs.decode(code.encode('ascii'), 'base64') UnicodeEncodeError: 'ascii' codec can't encode character '\xe0' in position 46: ordinal not in range(128)

During handling of the above exception, another exception occurred:
