開始在pytorch0.4.1版本下運行，各種出錯：
主要是形狀問題
svhn_train.py 119行。gen_feat_norm = gen_feat / gen_feat.norm(p=2, dim=1).reshape([-1,1]).expand_as(gen_feat) 加.reshape([-1,1])
utils.py中，21-25行 reshape([-1,1])
def log_sum_exp(logits, mask=None, inf=1e7):
if mask is not None:
logits = logits * mask - inf * (1.0 - mask)
max_logits = logits.max(1)[0]
return ((logits - max_logits.reshape([-1,1]).expand_as(logits)).exp() * mask).sum(1,keepdim=True).log().squeeze() + max_logits.squeeze()
else:
max_logits = logits.max(1)[0]
return ((logits - max_logits.reshape([-1,1]).expand_as(logits)).exp()).sum(1,keepdim=True).log().squeeze() + max_logits.squeeze()
model.py中多處 sum中加 ,keepdim=true 好幾個地方。
59 norm_weight = self.weight * (weight_scale.unsqueeze(1) / torch.sqrt((self.weight ** 2).sum(1) + 1e-6)).expand_as(self.weight)
111 norm_weight = self.weight * (weight_scale[:,None,None,None] / torch.sqrt((self.weight ** 2).sum(3).sum(2).sum(1) + 1e-6)).expand_as(self.weight)
166
norm_weight = self.weight * (weight_scale[None, :, None, None] / torch.sqrt((self.weight ** 2).sum(3).sum(2).sum(0) + 1e-6)).expand_as(self.weight)
好不容易調通了，但是結果中關鍵項爲00

後來終於知道 版本必須要跟作者要求一樣，於是乎大費周章的搞環境。
總結如下：conda create --name torch python=2.7
然後運行 source activate torch
然後：conda install tensorflow-gpu=1.4.1 (這裏需要注意 該版本需要cuda8支持，所以，如果不是cuda8，可以考慮再降版本）比如我的cua9.0 cudnn7.3.1,但是爲了滿足環境，我安裝tf 1.4.1版本。
然後 進入python 看看tf能不能導入 ，成功了繼續下一步
安裝pytorch，本來想最簡單的使用
conda install pytorch=0.1.12 torchvision cudatoolkit=8.0 -c pytorch 安裝，但是 安裝完後torch可以導入 但運行程序 提示 不能使用cuda。
我使用pip安裝，事先下載了 whl文件，一定注意版本對應。
https://pytorch.org/get-started/previous-versions/
https://download.pytorch.org/whl/cu80/torch-0.1.12.post1-cp27-none-linux_x86_64.whl 我下載的版本
直接 pip install 文件名 即可
然後進入python 可以導入成功
然後安裝 torchvision pip install torchvision=0.1.8 （版本跟torch對應的）
再運行原來的程序，好像只有一個 維度不對的提示。98-99 這裏 吧第二個維度[0]直接去掉 原來的是：
if data_set.labels[i][0] == 10:
data_set.labels[i][0] = 0
def preprocess(data_set):
for i in range(len(data_set.data)):
#print(i)
#print(data_set.labels[i])
if data_set.labels[i] == 10:
data_set.labels[i] = 0
preprocess(training_set)
preprocess(dev_set)
最終正確的結果應該是：

ssl-bad-gan python2到python3下後的代碼修改
修改後好多地方運行不出來原來效果。最終確定是版本原因，沒辦法折騰需要的版本。
Python報“TypeError: a bytes-like object is required, not ‘str’ ”解決辦法
今天在學習Python的時候，報了這樣一個錯誤，我先申明一下我用的python版本是3.7。
具體錯誤如下：
F:\Python3.7.0\python.exe F:/python/21.py
<class 'str'>
Traceback (most recent call last):

TypeError: a bytes-like object is required, not 'str'
上面最後一句話的意思是“類型錯誤：需要類似字節的對象，而不是字符串”。

今天在學習Python的時候，報了這樣一個錯誤，我先申明一下我用的python版本是3.7。
具體錯誤如下：
F:\Python3.7.0\python.exe F:/python/21.py
<class 'str'>
Traceback (most recent call last):
File "F:/python/21.py", line 10, in <module>
os.write(fd, str)
TypeError: a bytes-like object is required, not 'str'
上面最後一句話的意思是“類型錯誤：需要類似字節的對象，而不是字符串”。
TypeError: 'float' object cannot be interpreted as an integer
TypeError: 'float' object cannot be interpreted as an integer
解決方法：
在python2，/只留下了整數部分，去掉了小數，是int型。而在python3裏，/的結果是真正意義上的除法，結果是float型。所以便出現了Error Message: ‘float’ object cannot be interpreted as an integer。
In:
for i in range(r / M):
You're creating a float as a result - to fix this use the int division operator:
for i in range(r // M):
