ImportError: cannot import name ‘Model‘ from ‘torchkeras‘ 报错解决_importerror: cannot import name 'input' from 'kera

长话短说

官网相关包已经更新了，Model改成kerasmodel：

from torchkeras import Model,summary #Attention this line!
# 改一下库的名字
from torchkeras import kerasmodel,summary

记录过程

学习相关教程，需要使用torch、torchkeras两个包。
当晚通过以下指令下载了CPU版本的torch（去掉了末尾的-c pytorch据说才能用清华源下载）

conda install pytorch torchvision torchaudio cpuonly
1

结果就是产生一顿报错，搜集资料后顺利解决并运行代码。

1. ModuleNotFoundError: No module named 'torchkeras'

根据官网来，运行代码（10min左右）

pip install torchkeras
1

2. ImportError: cannot import name 'Model' from 'torchkeras' (s:\Anaconda\envs\py37\lib\site-packages\torchkeras\__init__.py)

我的操作是如下：关闭所有window>>重启VsCode>>再次执行安装命令：

pip install torchkeras
1

运行日志如下（这是又帮我装了torch？？）

本来以为到这里应该就可以了，结果一顿操作猛如虎，还是不行。在终端进行Python，试着import torchkeras 这个包，结果新的报错来了。

3. ModuleNotFoundError: No module named ‘PIL’

Finally，参考这篇博客报错：ModuleNotFoundError: No module named 'PIL’解决方法，总算是能在python端正常导入torchkeras，现象如下（没有回答就是最好的回答）：

D:\private\Motivated Learning\03Project\Fun_Rec>python
Python 3.8.7 (tags/v3.8.7:6503f05, Dec 21 2020, 17:59:51) [MSC v.1928 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import torchkeras

然而还是很烦，继续想导入Model的时候还是一样的报错，根本没动过。。。报错日志如下：

这个时候我注意到日志当中有个文件，点进去发现内容如下：

好家伙，搁这儿改名字呢！！！立即推！！！

from torchkeras import Model,summary #Attention this line!
# 改一下库的名字
from torchkeras import kerasmodel,summary #Attention this line!

结束，成功了。
