2、Debug 报下面错误&＃xff1a;

Traceback (most recent call last):File "D:\Program Files\JetBrains\PyCharm\helpers\pydev\_pydevd_bundle\pydevd_comm.py", line 393, in _on_runr &＃61; r.decode(&＃39;utf-8&＃39;)
UnicodeDecodeError: &＃39;utf-8&＃39; codec can&＃39;t decode bytes in position 1022-1023: unexpected end of data

解决方案&＃xff1a;

在pycharm中两个地方设置成utf-8&＃xff0c;页面右下角和File>setting中编码设置成UTF-8

参考&＃xff1a;pycharm中可以运行脚本但是不能debug脚本

pycharm debug出现UnicodeDecodeError: &＃39;utf-8&＃39; codec can&＃39;t decode 解决办法

第一处&＃xff1a;

上图右下角被水印覆盖掉&＃xff0c;去除的方式&＃xff1a;

自定义CSDN博客中图片上的水印内容

下面是插入图片的时候csdn-markdown编辑器中生成的代码&＃xff1a;

https://img.php1.cn/3cd4a/1eebe/cd5/011ac27956d007f0.webp?x-oss-process&＃61;image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3hyaW5vc3ZpcA&＃61;&＃61;,size_16,color_FFFFFF,t_70

注意&＃xff1a;这里的参数用Base64加密算法

对上面的链接作仔细观察&＃xff0c;发现有“&＃xff1f;x-oss-process&＃61;image”字样。接下来尝试把代码中“&＃xff1f;x-oss-process&＃61;image”后面的部分去掉&＃xff0c; 即&＃xff1a;

https://img.php1.cn/3cd4a/1eebe/cd5/011ac27956d007f0.webp?

 如下图&＃xff0c;便去掉了水印

第二处&＃xff1a;

若上述方法还不行&＃xff0c;试试下面的方法&＃xff1a; 

3、训练 rsgan 报如下错误&＃xff1a;

Traceback (most recent call last):File "E:/python/Tensorflow/随书资源/代码/12-9 rsgan.py", line 288, in showresult(163,"near",imagesv,x_nearestv)File "E:/python/Tensorflow/随书资源/代码/12-9 rsgan.py", line 61, in showresultypsnr&＃61;batch_y_psnr(conimg)File "E:/python/Tensorflow/随书资源/代码/12-9 rsgan.py", line 34, in batch_y_psnrpsnr&＃61;np.mean(20*np.log10(255.0/np.sqrt(mse)))
UnboundLocalError: local variable &＃39;mse&＃39; referenced before assignment

原因&＃xff1a;代码第34行  局部变量 mse 先调用    后定义 导致报错

解决办法&＃xff1a; 对调上图的两行代码

4、run out of memory 

Tensor Flow: Ran out of memory trying to allocate

Allocator (GPU_0_bfc) ran out of memory trying to allocate 2.14GiB. The caller indicates that this is not a failure, but may mean that there could be performance gains if more memory were available.

解决办法&＃xff1a; 减小 batch_size

5、在tensorflow训练model时&＃xff0c;添加 vgg_19 网络&＃xff0c;报下面错误&＃xff1a;

ValueError: Negative dimension size caused by subtracting 7 from 4 for &＃39;vgg_19/fc6/Conv2D&＃39; (op: &＃39;Conv2D&＃39;) with input shapes: [48,4,2,512], [7,7,512,4096].

原因&＃xff1a; vgg_19 的输入图片的大小应为  256x256x3 的图片&＃xff0c;若出入的不是这个 shape 就会报这个错误 

解决办法&＃xff1a; 通过 padding 或者 clip 将输入图片修改为 256x256x3 的图片

6  、AttributeError: &＃39;dict&＃39; object has no attribute &＃39;SerializeToString&＃39;

 参考&＃xff1a; TensorFlow报错&＃xff1a;&＃39;dict&＃39; object has no attribute &＃39;SerializeToString&＃39;

Traceback (most recent call last):File "main.py", line 37, in main(config)File "main.py", line 29, in maintrainer.train()File "/home/hyw/zp/tf/Pose-Guided-Person-Image-Generation-master/trainer.py", line 397, in trainself.generate(x, x_target, pose_target_fixed, self.model_dir, idx&＃61;step)File "/home/hyw/zp/tf/Pose-Guided-Person-Image-Generation-master/trainer.py", line 476, in generateG, G_1 &＃61; self.sess.run(self.G, self.G1, {self.x: x_fixed, self.pose_target: pose_target_fixed})File "/home/hyw/zp/anaconda2/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 884, in runcompat.as_bytes(options.SerializeToString())) if options else None
AttributeError: &＃39;dict&＃39; object has no attribute &＃39;SerializeToString&＃39;

原因&＃xff1a; 这个报错是因为sess.run&＃xff08;a&＃xff0c;b&＃xff0c;c&＃xff09;里要运行的多个变量没有用中括号括起来

解决办法&＃xff1a; 把run() 要运行的多个变量用中括号括起来&＃xff0c;即 sess.run([a,b,c], {x:x,y:y}

7、IOError: CRC check failed 0x49a91344 !&＃61; 0x6adf6a7L

Traceback (most recent call last):File "score.py", line 13, in import tflib.inception_scoreFile "/home/hyw/zp/tf/Pose-Guided-Person-Image-Generation-master/tflib/inception_score.py", line 101, in _init_inception()File "/home/hyw/zp/tf/Pose-Guided-Person-Image-Generation-master/tflib/inception_score.py", line 73, in _init_inceptiontarfile.open(filepath, &＃39;r:gz&＃39;).extractall(MODEL_DIR)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 2081, in extractallself.extract(tarinfo, path)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 2118, in extractself._extract_member(tarinfo, os.path.join(path, tarinfo.name))File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 2194, in _extract_memberself.makefile(tarinfo, targetpath)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 2235, in makefilecopyfileobj(source, target)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 266, in copyfileobjshutil.copyfileobj(src, dst)File "/home/hyw/zp/anaconda2/lib/python2.7/shutil.py", line 63, in copyfileobjbuf &＃61; fsrc.read(length)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 831, in readbuf &＃43;&＃61; self.fileobj.read(size - len(buf))File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 743, in readreturn self.readnormal(size)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 758, in readnormalreturn self.__read(size)File "/home/hyw/zp/anaconda2/lib/python2.7/tarfile.py", line 748, in __readbuf &＃61; self.fileobj.read(size)File "/home/hyw/zp/anaconda2/lib/python2.7/gzip.py", line 267, in readself._read(readsize)File "/home/hyw/zp/anaconda2/lib/python2.7/gzip.py", line 314, in _readself._read_eof()File "/home/hyw/zp/anaconda2/lib/python2.7/gzip.py", line 353, in _read_eofhex(self.crc)))

IOError: CRC check failed 0x49a91344 !&＃61; 0x6adf6a7L

原因分析&＃xff1a; 通过使用 vscode 中的 go to  defination 查看 import tflib.inception_score 中的 inception_score 模块中的函数&＃xff0c;发现里面有个需要下载的文件链接&＃xff0c;要下载  inception-2015-12-05.tgz&＃xff0c;结合报错中出现了 tarflie 和 gzip 这些和解压压缩有关模块&＃xff0c;所以初步怀疑&＃xff0c;是文件不存在或者 下载的文件有缺陷造成的

到ubuntu 的 /tmp/imagenet 目录下查看 发现 inception-2015-12-05.tgz 这个文件只有 2.3M&＃xff0c;而真实大小应该是 88.9M&＃xff0c;所以怀疑该文件并未下载完整&＃xff0c;导致的莫名错误

解决办法&＃xff1a; 手动下载 inception-2015-12-05.tgz 文件&＃xff0c;放到  /tmp/imagenet  目录下&＃xff0c;问题解决

提醒一点&＃xff1a; 报  IO错误    无非就是 文件  或者  路径目录  找不到

参考&＃xff1a; python open打开文件失败 IOError: [Errno 2] No such file or directory: &＃39;E://aaa.txt&＃39;
