一定要把PythonAPI目录下除setup.py之外的所有文件拷贝到pytorch-deeplab-xception-master文件夹下

出现问题
ImportError: No module named ‘Queue’

出现问题
from utils.loss import SegmentationLosses
ImportError: No module named loss

解决
在utils文件下 新建一个空白的__init__.py

出现问题
AttributeError: ‘module’ object has no attribute ‘kaiming_normal_’

然后 我删除了所有pyc文件 （主要是不敢更新Python27\Lib\urllib2.pyc文件 怕影响别的算法）
删除指令 find /dir -name “*.pyc” | xargs rm -rf
但并没用

然后
我又配了一个python3.5 pytorch0.4.1的环境

出现问题
RuntimeError: CUDA error: out of memory
解决
train.py中改batch-size的default=2

出现问题
ValueError: Expected more than 1 value per channel when training, got input size [1, 256, 1, 1]

模型中含有nn.BatchNorm层，训练时需要batch_size大于1，来计算当前batch的running mean and std，数据数量除以batch_size后刚好余1时就会报错。

解决
改batch_size 使其除完不余1，但我改完5之后内存又不行了，报错。
于是 我去找了/usr/local/lib/python3.5/dist-packages/torch/utils/data/dataloader.py文件，改里面drop_last=True。
因为远程服务器不能直接打开这个文件，所以粘过来又拷过去的。
