--ss-patch-sizePatch size for the convolution kernel. This is the size of patches in the feature encoding, not the full size image, so small values like 3 or 5 will typically work well. --ss-strideStride for the patch kernel. Setting this equal to patch size will extract non-overlappin...

pytorch读取imagenet pytorch读取tfrecord,相信大家大部分还在使用tf,placeholder来进行数据的读入,虽然这种方法很直观,但是效率比较低。事实上TensorFlow有三种数据读入的方式,在我们的不断的学习中我们应该不断的升级我们的认知,将学习的进度从直观、方便转入高效的

Fast Run The organization structure of the code is very simple. You can directly run python test.py to test the SR performance of TFMAN model trai...
正如人类历史的发展一样,深度学习框架经过一轮激烈的竞争,最终形成了两大「帝国」:TensorFlow 和 PyTorch 的双头垄断,这两大「帝国」代表了深度学习框架研发和生产中 95% 以上的用例。2019 年,Chainer 团队_将他们的开发工作转移到 PyTorch;类似地,微软_停止了 CNTK 框架的积极开发,部分团队成员转而支持 Windows 和...

我想计算tf.extract_volume_patches的逆。使用渐变(如和中所建议的)计算tf.extract_volume_patches的逆对于静态已知的输入形状有效,但是在用于可变输入形状时会返回错误。一个合成3DMNIST数据集的最小示例(它在input=(28,28,28,1)时有效,但我需要在可变大小的数据输入(大型生物医学图像)上提取): import tensorflow...
