华为极客周活动-昇腾万里--模型王者挑战赛VQVAE调通过程 下

现在的进展问题：

1 依瞳系统暂停之后，再开，那些文件又要重新打一遍补丁

2 issue3还没有解决，要持续关注这个issue https://gitee.com/ascend/modelzoo/issues/I28YYG

Issue3 解决过程

经排查，QueueDequeueMany输出shape与TF不一致系上游算子RandomShuffleQueue中shapes属性未向下传递导致

已联系负责该算子的开发人员进行修复

问已经解决，请替换附件中的文件至如下目录，替换前请先备份。

/home/HwHiAiUser/Ascend/ascend-toolkit/20.1.rc1/arm64-linux/opp/op_proto/built-in/libopsproto.so

这样issue3已经解决，又打一个补丁文件。

Issue4 报错（AOE）

打上issue3的补丁，还是报错。由于时间有点久，那个报错也没有什么特征性的东西，所以从log上看不出是否修正了我以前的那个bug。原谅我有时候也偷懒，没有仔细比对报错信息。

发现aoe已经提交issue了，我在升级完issue的补丁后，我们的报错信心一样，于是就持续关注这个issue和解决方案，这个也算是issue4了：

https://gitee.com/ascend/modelzoo/issues/I2A7SC

返回信息，可以参考下方链接中“sess.run模式下开启混合计算”的方式将tf.train.shuffle_batch和tf.train.string_input_producer设置为不下沉，再试试网络是否可以跑起来

https://support.huaweicloud.com/mprtg-A800_9000_9010/atlasprtg_13_0033.html

说用下混合计算，看到文档里说混合计算模式下，iterations_per_loop必须为1。不过我在代码里没有找到这个关键字，那是否意味着我不用考虑iterations_per_loop的实际取值呢？（后来通过沟通知道，混合模式iterations_per_loop就已经设为1了）

用户还可通过without_npu_compile_scope自行配置不下沉的算子。

于是按照说明修改代码82行：

# change to 不下沉

with npu_scope.without_npu_compile_scope():

filename_queue = tf.train.string_input_producer(filenames,num_epochs=num_epochs)

因为AOE的问题解决了，他的issue关闭，但是我的问题还没解决，所以我报了自己的issue4：

Issue4报错

后来无法复现，就关闭了。但是今天又复现了。

发现原来依瞳系统下面，python和python3.7指向竟然不是同一个。

model_user14@f2e974f6-0696-4b25-874d-3053d19ba4e2:~/jk/tf-vqvae$  which python

/usr/bin/python

model_user14@f2e974f6-0696-4b25-874d-3053d19ba4e2:~/jk/tf-vqvae$  which python3.7

/usr/local/bin/python3.7

model_user14@f2e974f6-0696-4b25-874d-3053d19ba4e2:~/jk/tf-vqvae$ which pip

/usr/local/bin/pip

因此应该用usr/local/bin这个目录下的python，也就是python3.7

检查tf.train.batch里面的设置，尤其是allow_smaller_final_batch的设置，发现一共出现3处，唯一起作用那处已经改成了False

images,labels = tf.train.batch(

[image,label],

batch_size=BATCH_SIZE,

num_threads=1,

capacity=BATCH_SIZE,

allow_smaller_final_batch=False)

将代码改成非aoe模式，因为aoe他的规避方式不复合比赛的要求。

将其它两处train.Batch 改成了不下沉。混合计算里的不下沉，就是将不下沉的语句用这个语句包起来：

with npu_scope.without_npu_compile_scope():

由于修改好几个地方，程序被改的面目全非，因此又重新测试cpu代码，发现cifar10的cpu代码竟然也不通过了（这就是vqvae这个模型难的地方，改一点点地方，报错就不一样，甚至感觉没改哪些地方，它自己也会莫名其妙的不通了）。

又废了好大劲才终于又调通了cpu代码。Cpu代码程序单独写为cifar_base.py。然后再比着调通npu程序代码，也就是如果把npu相关代码都屏蔽掉，npu程序也是能跑通的。

Issue5的报错，是shape没有对齐

https://gitee.com/ascend/modelzoo/issues/I2AVI5

应该是data batch那里没有把最后一段丢弃的缘故，

images,labels = tf.train.batch(

[image,label],

batch_size=BATCH_SIZE,

num_threads=1,

capacity=BATCH_SIZE,

allow_smaller_final_batch=False)

加上黑体部分就ok了。

报issue5.1

https://gitee.com/ascend/modelzoo/issues/I2B2US

提到：麻烦以后出现DEVMM报错时，敲dmesg获取一下内核日志，方便定位，谢谢~

[ERROR] DEVMM(25538,python3.7):2020-12-27-12:52:10.065.876 [hardware/build/../dev_platform/devmm/devmm/devmm_svm.c:268][devmm_copy_ioctl 268] Ioctl(-1060090619) error! ret=-1, dst=0xfffed40af2a0, src=0x1008000bc000, size=112,

但是这个问题并不容易复现，在我的系统里偶尔能复现，在研发那块复现也很困难。

结果元旦后第一个工作日：新年新气象，今天略微修改了下代码，竟然跑通了，我都很惊讶。

数据读取部分用了混合计算不下沉，原则上没有修改骨干代码 ，但是元旦那天还不行，今天稍微改了下代码，就跑通了 。

这个issue的问题解决了，关闭。

上面的记录文字很短，其实这个issue花费的时间非常多，从2020年的年尾，一直到2021年的年初，两头占着算两年时间，中间代码改的面目全非，bug的样子也是日新月异，可以说最后成功的喜悦有多大，中间的情绪低落就有多深。

还没有完成的issue6 报错

这回的报错没有提交issue6 。

查找，发现有可能是没有正确初始化导致的，于是加上这句试试：

sess.graph.finalize()

还是同样的报错。

Main代码：

init_op = tf.group(tf.global_variables_initializer(),

tf.local_variables_initializer())

# >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Run!

config = tf.ConfigProto()

# config.gpu_options.allow_growth = True

custom_op =  config.graph_options.rewrite_options.custom_optimizers.add()

custom_op.name =  "NpuOptimizer"

custom_op.parameter_map["use_off_line"].b = True #在昇腾AI处理器执行训练

custom_op.parameter_map["mix_compile_mode"].b =  True

config.graph_options.rewrite_options.remapping = RewriterConfig.OFF  #关闭remap开关

sess = tf.Session(config=config)

# sess.graph.finalize()

sess.run(init_op)

print("="*1000, "run sess.run(init_op) OK!")

summary_writer = tf.summary.FileWriter(LOG_DIR,sess.graph)

# logging.warning("dch summary_writer")

summary_writer.add_summary(config_summary.eval(session=sess))

# logging.warning("dch summary_writer.add")

extract_z代码：

with npu_scope.without_npu_compile_scope():

images,labels = tf.train.batch(

[image,label],

batch_size=BATCH_SIZE,

num_threads=1,

capacity=BATCH_SIZE,

allow_smaller_final_batch=False)

# <<<<<<<

# images = images.batch(batch_size, drop_remainder=True)

# >>>>>>> MODEL

with tf.variable_scope('net'):

with tf.variable_scope('params') as params:

pass

x_ph = tf.placeholder(tf.float32,[BATCH_SIZE,32,32,3])

net= VQVAE(None,None,BETA,x_ph,K,D,_cifar10_arch,params,False)

init_op = tf.group(tf.global_variables_initializer(),

tf.local_variables_initializer())

# >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Run!

config = tf.ConfigProto()

# config.gpu_options.allow_growth = True

custom_op =  config.graph_options.rewrite_options.custom_optimizers.add()

custom_op.name =  "NpuOptimizer"

custom_op.parameter_map["use_off_line"].b = True #在昇腾AI处理器执行训练

custom_op.parameter_map["mix_compile_mode"].b =  True # 测试算子下沉

config.graph_options.rewrite_options.remapping = RewriterConfig.OFF  #关闭remap开关

sess = tf.Session(config=config)

logger.warn('warn sess = tf.Session(config=config)')

# sess = tf.Session()

sess.graph.finalize()

sess.run(init_op)

logger.warn('warn sess.run(init_op)')

最终采用将这句话里的epoch=1参数去掉，终于能够通过了 。

# image,label = get_image(num_epochs=1)

image,label = get_image()

这个解决方法可能不是最终解决方法，先这样处理。

这个问题现在还没有解决，完全不知道问题出在哪里。 大约跟数据的喂入有关系，但是我目前解决不了，只能先设为8：config['TRAIN_NUM'] = 8保证整个程序能跑通，这个issue先留着吧。

PR提交，最后的冲刺

经过艰苦卓绝的奋斗，终于迎来了模型大赛的曙光，整个模型能够在升腾系统上跑通了，而且基本符合大赛的要求。后面就是一些微调了。

审核方给的修改意见

1 程序设置了对tf.train.string_input_producer这个的不下沉

要把这个去掉，只开启混合计算

2 VQ-VAE的网络问题：网络结构中数据预处理的方式是通过这个循环控制的，这个循环在数据达到上限后抛出异常，根据异常来结束处理，目前在昇腾产品执行会core。请开发者自行修改成其他控制流程：

while not coord.should_stop():

x,y = sess.run([images,labels])

k = sess.run(net.k,feed_dict={x_ph:x})

ks.append(k)

ys.append(y)

print('.', end='', flush=True)

except tf.errors.OutOfRangeError:

VQVAE PR最后的整改

1 整个程序只启动混合计算，把单独的不下沉设置全部去掉。（也就是最终的使用方法，理论上系统把支持的全部下沉，不支持的默认就能不下沉，不需要用户手动设置）

2 将while循环改成for循环

for step in tqdm(xrange(TRAIN_NUM), dynamic_ncols=True):

x,y = sess.run([images,labels])

k = sess.run(net.k,feed_dict={x_ph:x})

ks.append(k)

ys.append(y)

并设置循环步数：

config['TRAIN_NUM'] = 24

再跟少芳那边沟通了一下，第二部分能通过就是将get_image函数参数去掉解决的，反正已经设置了循环步数，这里应该不影响整体。

修改： # image,label = get_image(num_epochs=1)

修改为： image,label = get_image()

然后提交PR，终于PR验收通过啦！乌拉！非常激动！结果并不重要，中间出现问题、解决问题的过程最重要。但是如果没有结果，这篇文档都师出无名，中间付出的精力可能就白白付出了，学到的东西可能也没现在这么多、印象这么深刻。

VQVAE 模型tensorflow迁移到升腾总结

本次大赛主要经历了报名、模型选择、模型迁移、排错、提交PR等几个阶段，具体过程如前面篇幅所讲，一言难尽啊！

本次模型迁移大赛是很好的一次学习和锻炼的机会，我原来对tensorflow一点都不懂，经过这次比赛，不管懂不懂，反正代码看了好多遍，tf程序的流程也懂了一点。升腾系统原来也只是在Modelarts的notebook和训练任务中有接触，像这次这样可以在依瞳系统里自由的安装软件、完全控制系统还是第一次。在排错的过程中，跟华为研发有了第一线接触，为及时准确的排错能力！对升腾系统和MindSpore AI框架充满信心！

模型大赛的白银赛段很快就要来了，大家快准备报名吧！
