Single GPU training script error #30

Closed emushtaq closed 6 years ago

emushtaq commented 6 years ago

Hello

I am trying to run the training script on the SVHN dataset with the following command: python chainer/train_svhn.py curriculum.json /logs --char-map datasets/svhn/svhn_char_map.json --blank-label 0 -b 10 -g 0

I get the following error

/usr/local/lib/python3.5/dist-packages/h5py/init.py:36: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type. from ._conv import register_converters as _register_converters Traceback (most recent call last): File "chainer/train_svhn.py", line 147, in updater = StandardUpdater(iterator=train_iterators, optimizer=optimizer, device=args.gpus) File "/usr/local/lib/python3.5/dist-packages/chainer/training/updater.py", line 144, in init if device is not None and device >= 0: TypeError: unorderable types: list() >= int() Exception ignored in: <bound method MultiprocessIterator.del of <chainer.iterators.multiprocess_iterator.MultiprocessIterator object at 0x7fbddd666c50>> Traceback (most recent call last): File "/usr/local/lib/python3.5/dist-packages/chainer/iterators/multiprocess_iterator.py", line 117, in del File "/usr/local/lib/python3.5/dist-packages/chainer/iterators/multiprocess_iterator.py", line 242, in terminate AttributeError: 'NoneType' object has no attribute 'STATUS_TERMINATE' Exception ignored in: <bound method MultiprocessIterator.del of <chainer.iterators.multiprocess_iterator.MultiprocessIterator object at 0x7fbddd666d68>> Traceback (most recent call last): File "/usr/local/lib/python3.5/dist-packages/chainer/iterators/multiprocess_iterator.py", line 117, in del File "/usr/local/lib/python3.5/dist-packages/chainer/iterators/multiprocess_iterator.py", line 242, in terminate AttributeError: 'NoneType' object has no attribute 'STATUS_TERMINATE'

Please help resolve. Thanks!

Bartzi commented 6 years ago

This is your problem: TypeError: unorderable types: list() >= int() It means that you gave a list with one element to the StandardUpdater. You have to provide only a single integer, by i.e. writing StandardUpdater(iterator=train_iterators, optimizer=optimizer, device=args.gpus[0])

emushtaq commented 6 years ago

Thanks!

I made a few more changes to get it working on one GPU. Line https://github.com/Bartzi/see/blob/edcde78993dfde0f79d120252b7edfd440944a9b/chainer/train_svhn.py#L193 and https://github.com/Bartzi/see/blob/edcde78993dfde0f79d120252b7edfd440944a9b/chainer/train_svhn.py#L206 , changing them to updater.device.

I now have a Cupy NVRTC error.

Bartzi commented 6 years ago

Hmm, seems like your CUDA environment is either not correctly installed, or your paths to the CUDA toolkit are not set correctly... but that is just a guess. Its definitely a problem with your development environment.

emushtaq commented 6 years ago

Ok. I’ll try setting it up again and giving it another go. Closing till then. Thanks for your help.

emushtaq commented 6 years ago

Tried a completely new setup.

I changed the following to make it run on a single GPU. updater = StandardUpdater(iterator=train_iterators, optimizer=optimizer, device=args.gpus[0]) It seems to be causing a segmentation fault. Any idea why this may be happening.

emushtaq commented 6 years ago

was running the training script with the flag -g 0 in the single GPU case. This seems to be the reason for the above error.

emushtaq commented 6 years ago

After resolving a few environment issues, stumbled into this error. Help appreciated.

Bartzi commented 6 years ago

Yeah I see the problem. You changed the Updater and I did not tell you that you'll also need to change this line to train_iterators = chainer.iterators.MultiprocessIterator(gpu_datasets[0], args.batch_size). The StandardUpdater can not handle a list of iterators, but needs just one.

emushtaq commented 6 years ago

ah. But this leads to a segmentation fault with the trainer.run() call. Not sure what's happening

Bartzi commented 6 years ago

interesting, maybe it works better with a Docker Container?

emushtaq commented 6 years ago

I'll try the docker container and get back.

emushtaq commented 6 years ago

Tried the docker file to start fresh, still having the same error. This is the gdb backtrace of the segmentation fault.

there is something going wrong in numpy, maybe your installation is faulty? Something on your machine that is causing the troubles?

Yes, it's getting pretty hard to debug these environmental issues. Anyways, I tried to uninstall numpy and installed it again. This is the new error stack

Bartzi commented 6 years ago

so far so good, did you make any changes in the code? You should not run out of memory if you are using the original code, the provided svhn data and a batch size like you use.

emushtaq commented 6 years ago

Not really, I made a fresh clone of the repo and just changed the file paths to load the images properly (my docker specific settings where causing a 'could not load file' error)

This is the only change made:

in file_dataset.py

def load_image(self, file_name):
        file_name = os.path.basename(file_name) --> NEW LINE TO CORRECT FILEPATH
        with Image.open(os.path.join(self.base_dir, file_name)) as the_image:
Bartzi commented 6 years ago

Hmm, the only thing I can think of is that some part of the code is keeping a reference to some GPU data... it might help to have a look at the memory usage of the GPU with watch -n 0.5 nvidia-smi and see whether the network seems to be trained for more than one iteration. If that is the case your problem is related to something like that.

Otherwise I don't know really know what is causing your problem...

Bartzi commented 6 years ago

You could try to debug it and run each layer of the network in the debugger and examine the memory usage in order to identify the part where you get that problem...

emushtaq commented 6 years ago

OK, thanks, I will give it a shot. But before that, I will try an alternate GPU. Just to double check.

emushtaq commented 6 years ago

Finally got a trained network with a diff GPU! 🎉 Could be that I had issues with GPU references like you suggested. Unsure though. Thanks for all your time. Next Step, Evaluation and visualizing the results :)

Bartzi commented 6 years ago

I hope all goes well!

kartherion commented 6 years ago

I also meet the same problem in single GPU, I have modified the scripts(train_svhn.py) mentioned above, but the terminal outputs this: cupy.cuda.driver.CUDADriverError: CUDA_ERROR_UNKNOWN: unknown error do you have any idea?

cupy.cuda.driver.CUDADriverError: CUDA_ERROR_UNKNOWN: unknown error
Bartzi commented 6 years ago

can you do nvidia-smi on your machine? Do any of the CUDA examples work?

kartherion commented 6 years ago

I have mad the CUDA success on caffe/mxnet and other structures, the CUDA examples also can be done well. 2018-05-25 16-21-34

Bartzi commented 6 years ago

Hmm, good question then. I think it is because of your environment. Did you check that you have the most recent driver and cudnn for this driver installed? You could tryo to reinstall cupy with verbose output and check for anything that seems odd. But other than that I can not tell you what the problem is.
