我正在使用hyperas
模块来调整我的Keras
模型并返回错误:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 4785: ordinal not in range(128)
调用地点发生错误,语法为trials
:
if __name__ == '__main__':
best_run, best_model = optim.minimize(model=create_model,
data=data,
algo=tpe.suggest,
max_evals=20,
trials=Trials())
我认为问题的根源是由于我加载的 numpy .npy 文件是ascii
编码格式数据。那么,如何将ascii
格式更改为utf-8
格式?
我通过添加看到了一些这样的解决方案,encoding='latin1'
但它不起作用。
label =np.load(os.getcwd()+'/Simu_Sample_label_1000.npy',encoding="latin1")
sample=np.load(os.getcwd()+'/Training_Sample_1000.npy',encoding="latin1")
在此处添加我的整个回溯:
In [3]: %run 1dCNN.py

我想我最好把所有的traceback放在这里,所有的代码如下: https ://github.com/MinghaoDu1994/MyPythonFunctions/blob/master/1Dcnn
我认为问题是由于 中的功能Trials
,hyperopt
但我没有找到像我这样的相关问题。
