Hi there! I'm having trouble to run this bash shells/create_dataset.sh

The error is this: patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 patch size: 92 24 16 n_all_files: 0 patches: 0 Traceback (most recent call last): File "tests/test_dataset.py", line 36, in o_val, dtype=np.uint8).reshape((92, 92, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_dataset.py", line 36, in o_val, dtype=np.uint8).reshape((92, 92, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_dataset.py", line 36, in o_val, dtype=np.uint8).reshape((92, 92, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_dataset.py", line 36, in o_val, dtype=np.uint8).reshape((92, 92, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_transform.py", line 55, in (args.ortho_original_side, args.ortho_original_side, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_transform.py", line 55, in (args.ortho_original_side, args.ortho_original_side, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_transform.py", line 55, in (args.ortho_original_side, args.ortho_original_side, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3) Traceback (most recent call last): File "tests/test_transform.py", line 55, in (args.ortho_original_side, args.ortho_original_side, 3)) ValueError: cannot reshape array of size 0 into shape (92,92,3)

Any ideas? Thank you very much for your time!

Hi,

I am trying set Adam optimization algorithm but receiving the following error, can you please help me how to set parameters?

python3.5/site-packages/chainer-1.22.0-py3.5-linux-x86_64.egg/chainer/optimizers/adam.py", line 51, in lr return self.alpha * math.sqrt(fix2) / fix1 ZeroDivisionError: float division by zero

Please see the below parameters what i have set.

parser.add_argument('--opt', type=str, default='Adam', choices=['MomentumSGD', 'Adam', 'AdaGrad'])
parser.add_argument('--weight_decay', type=float, default=0.0001)

Thank you

This project use Chianer as its deep learning framework. However, Chianer is based on a Cuda driver named CUPY, which is(seemingly) not supported by any Anaconda library. Therefore setup environment using anaconda will always result in fail to find cupy module.

I tried to using system python cupy library and conda chainer library with no luck. If any one has solution, please follow this issue.

I am using python 3.6 on win 10 I run the script create_dataset Found this Error ModuleNotFoundError: No module named 'utils.patches' the Error relates to this lines: from utils.patches import divide_to_patches

Kindly help..

Hi,

I have tested an algorithm on Tesla p100 (Ubuntu Server16.04 LTS x86_64) and it takes one epoch 2Hrs. I applied same algorithm on Quadro M4000 (Ubuntu desktop 16.04 LTS x86_64) takes 2Hrs 40min.

We expected that training time will comedown to half of the Quadro M4000 but their no much difference between Tesla p100 and Quadro M4000.

Please give me guidance so that the training time will be reduced. I appreciate you kind help

Hi, I'm trying to train my own dataset but failed to deploy after many different CUDA, CUDNN, CuPy, Python version trials on Ubuntu 16.04 on NVIDIA GTX-950M.

Is there any updated environment versions for CUDA, CUDNN, CuPy, Python, Chainer, NumPy?

Cheers,

Hello,

I am currently trying to automate parts of this project and I am running into difficulties during the training phase using CPU mode, which throws an IndexError and appears to hang the entire training. I am using a very small dataset from the mass_buildings set, i.e. I am using 8 training images and 2 validation images. The purpose is only to test and not to have accurate results at the moment. Below is the state of the installation and steps I am using:

System:

uname -a
Linux user-VirtualBox 4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Python (w/o Anaconda):

$ python -V
Python 3.5.2

Python modules:

[email protected]:~/Source/ssai-cnn$ pip3 freeze
...
chainer==1.5.0.2
...
Cython==0.23.4
...
h5py==2.7.1

...
numpy==1.10.1
onboard==1.2.0
opencv-python==3.1.0.3
...
six==1.10.0
tqdm==4.19.5
...

Additionally, Boost 1.59.0 and OpenCV 3.0.0 have been build and installed from source and both installs appears successful. The utils is also built successfully.

I have downloaded only a small subset of the mass_buildings dataset:

# ls -R ./data/mass_buildings/train/
./data/mass_buildings/train/:
map  sat

./data/mass_buildings/train/map:
22678915_15.tif  22678930_15.tif  22678945_15.tif  22678960_15.tif

./data/mass_buildings/train/sat:
22678915_15.tiff  22678930_15.tiff  22678945_15.tiff  22678960_15.tiff

Below is the output obtained by running the shells/create_datasets.sh script, modified only to build the mass_buildings data:

patch size: 92 24 16

0.03437542915344238 sec (128, 3, 64, 64) (128, 16, 16)

Then the training script is initiated using the following command:

[email protected]:~/Source/ssai-cnn$ CHAINER_TYPE_CHECK=0 CHAINER_SEED=$1 \
> nohup python ./scripts/train.py \
> --seed 0 \
> --gpu -1 \
> --model ./models/MnihCNN_multi.py \
> --train_orthokill _db data/mass_buildings/lmdb/train_sat \
> --train_label_db data/mass_buildings/lmdb/train_map \
> --valid_ortho_db data/mass_buildings/lmdb/valid_sat \
> --valid_label_db data/mass_buildings/lmdb/valid_map \
> --dataset_size 1.0 \
> --epoch 1

As you can see above, I've been using only 8 images and a single epoch. I left the entire process run an entire night and never completed. Hence the reason I believe the process simply hanged. Using nohup also does not complete. When forcefully stopped using Ctrl-C, I'm obtaining the following message:

# cat nohup.out 
Traceback (most recent call last):

    return self.forward_cpu(inputs)

    p = yd[six.moves.range(t.size), numpy.maximum(t.flat, 0)]
IndexError: index 76 is out of bounds for axis 1 with size 3

This is the only components that fails at this moment. I've tested the prediction and evaluation phases using the pre-trained data and both seems to complete successfully. Any assistance on how I could use the training script using custom datasets would be appreciated.

Thank you

I am running the training process on dataset of 430 images (Resolution 1500X1500 pixels) CUDNN is configured cuda.cudnn_enabled gives True Training doesn’t run fine in CPU environment . While using GPU environment using the flag CHAINER_CUDNN = 0 (i.e. cudnn disabled) it gives warning message about cudnn and the GPU usage shows only max. 25%. I feel it is not utilizing the GPU environment fully during training as 1 EPOCH takes 2-3 hrs on average, assuming this for 400 epochs it would take us too many 800-1200hrs (33-50 days) to complete the training. +++ Warning message showing CuDNN not enabled for training+++ /home/user/anaconda3/envs/ssai-cnn/lib/python3.5/site-packages/chainer/cuda.py:85: UserWarning: cuDNN is not enabled.

I just want to confirm if your process had run on cudnn enabled mode is yes then what chainer and cupy and other supporting package versions were used? What will be the challenges on existing code if I have to upgrade the Chainer version 3.0.0 or 3.1.0 , Cupy 2.1.0 and other packages? Which chainer-cupy version combination will be preferable?

Thanks

Hi, I use Windows 10, anaconda3 and Python 3.6 I was wondering if i would be able to build the utils if I change the paths in the file build.sh. e.g. $PYTHON_DIR/lib/libpython3.5m.so to Windows Anaconda equivalent (if there is one). then run bash using cygwin.

Or should I give up and use a Linux machine? Thanks, Véro
