chrishkchris opened a new pull request #523: SINGA-478 Improve __itruediv__ in tensor.py URL: https://github.com/apache/incubator-singa/pull/523 Improve the __itruediv__ operation by using the /= operator in c tensor directly instead of *= operator. Has tested two cases (because for end to end purpose): Case 1. simple tensor division in ncrf docker container ```python from singa import tensor from singa import device import numpy as np Y = np.ones(shape=[10],dtype=np.float32) * 10.0 y = tensor.from_numpy(Y) y.to_device(device.get_default_device()) y.to_device(device.create_cuda_gpu_on(1)) def divide(y): y /= 10 divide(y) print(tensor.to_numpy(y)) ``` Result ``` root@26c9db193eb0:~/incubator-singa# python3 /root/incubator-singa/python/singa/test.py [1. 1. 1. 1. 1. 1. 1. 1. 1. 1.] ``` Case 2. 8 GPUs mnist distributed training in AWS (i.e. mnist_dist_demo.py)
