英文:
SyntaxError in "from keras.utils import to_categorical"
问题
在运行涉及关系抽取的代码时遇到问题。我的环境是Python2.7.17，VScode中的Python扩展版本是2022.2.1924087327。我不知道为什么会出现SyntaxError。当我搜索关于from keras.utils import to_categorical的问题时，几乎所有的答案都是将其更改为from tensorflow.keras.utils import to_categorical。但这与我的问题不同。有人能帮我吗？
当我想在Python 2.7.17而不是3.7中运行代码时，我应该怎么做？

I have a problem when I try to run the code which is about a Relation Extraction. My environment is Python2.7.17. The version of python extention in VScode is 2022.2.1924087327.
I dont know why it occurs SyntaxError. When I search the problem about from keras.utils import to_categorical, almost all the answer is to change it into from tensorflow.keras.utils import to_categorical. But it is different from My problem.
Can anybody help me?
When I want to run the code in Python 2.7.17 not 3.7, what should I do?

无法在Python==2或Python<3.6上使用keras，因为keras使用f-strings：
from keras.utils import to_categorical
File "/home/user/.pyenv/versions/2.7.18/lib/python2.7/site-packages/keras/distribute/sidecar_evaluator.py", line 195
f"{_CHECKPOINT_TIMEOUT_SEC} seconds. "
^
SyntaxError: invalid syntax
英文:
You can't use keras with neither Python==2 nor Python<3.6 because keras use f-strings:
In [1]: from keras.utils import to_categorical
File "/home/user/.pyenv/versions/2.7.18/lib/python2.7/site-packages/keras/distribute/sidecar_evaluator.py", line 195
f"{_CHECKPOINT_TIMEOUT_SEC} seconds. "
