代码复现环境报错

[acadaiaca]

复现代码，在docker容器内运行或者新建环境，都会在bert_model = load_trained_model_from_checkpoint(paths.config, paths.checkpoint, seq_len=None) 这步报错：AttributeError: 'tuple' object has no attribute 'layer'
所有依赖和requirements.txt里要求的一样，尝试安装了tensorflow_gpu=1.14和1.13，都会报同样的错误，请问是什么情况？
报错信息：
`>>> from keras_bert import load_vocabulary, load_trained_model_from_checkpoint, Tokenizer, get_checkpoint_paths

新建虚拟环境的安装步骤：pip install tensorflow-gpu==1.14
pip install -r requirements.txt
`
安装环境我是少了什么步骤吗？

[beader]

你尝试直接用我的镜像试试

docker pull beader/tensorflow:nightly-gpu-py3-jupyter

[acadaiaca]

你尝试直接用我的镜像试试

docker pull beader/tensorflow:nightly-gpu-py3-jupyter

您好，直接使用镜像运行model1的代码，同样在载入模型load_trained_model_from_checkpoint这步出现了相同的报错：AttributeError: 'tuple' object has no attribute 'layer'
查阅了一下说是tf.keras和tf混用，可能是环境版本问题
tensorflow-gpu==1.14
keras==2.2.4
keras-bert==0.68.1

[beader]

@acadaiaca 抱歉，这个项目已经很久了，而且我手边也没有设备，没法协助你，抱歉。你主要参考模型的一些大概思路，然后自己去implement会比较好。

[acadaiaca]

@beader 非常感谢！目前问题已经解决，通过直接拷贝其他人能成功复现代码的环境包。该环境问题大概率是后来keras2.24经过改版之后造成与tf不兼容。

[acadaiaca]

@lgc1462 你好，请问你安装环境也遇到相同问题了吗，keras_bert包的问题？可以发你，给我你的邮箱

[wudipapa]

@acadaiaca 你好，请问可以也发我一份吗?

[nuo-mi]

@acadaiaca 您好，能麻烦您也给我发一份能复现代码的环境包么？谢谢您，piaodongyuhg@gmail.com

您好，请问可以提供一下这个安装环境的requestment.txt文档么，谢谢您，ccfuncy@163.com

[HiFallMaple]

@acadaiaca 您好，能否也把能復現代碼的包給我一份呢？非常感謝

[LurenRen1102]

我说一下自己的解决思路：
在整个项目中很多地方都出现了AttributeError，很多查询后都说是混用了keras和tf.keras的包，但作者的代码里并没有混用
在我多次定位排查后发现是keras包内部的一些问题，在这些报错信息的trace back中可以找到一些文件，其import部分包含了一些首字母大写的名称的模块，这些模块点进去后可以发现其引用只有两行：
from tensorflow import keras
from tensorflow.keras import ***（可能记得不是很清楚，但确实是引用了tf.keras）
将这些部分改成引用纯keras模块，大概有六七个此类文件可以更改，改完之后解决报错
如果有新的类似报错还是去trace里找上述类型的文件去看import部分，不过在更改之前还是建议百度一下，一些错误不一定也是这个原因，此方法只解决混用导致的报错
希望可以帮到碰到此类问题的朋友

@acadaiaca 你好，能否把这个keras包发我邮箱986025376@qq.com ？非常感谢！

如果没有使用docker的条件，可以用conda create --name nl2sql tensorflow-gpu==1.15, 然后安装上述依赖，亲测可以跑通
