Python3:ImportError: No module named 'compiler.ast'
from compiler.ast import flatten
上面這條語句好像在python3 以后就廢除了,如果使用的話就會報錯。
Traceback (most recent call last):
File "eval_ssd_network.py", line 31, in <module>
from compiler.ast import flatten
ImportError: No module named 'compiler'
或者
Traceback (most recent call last):
File "eval_ssd_network.py", line 31, in <module>
from compiler.ast import flatten
ImportError: No module named 'compiler.ast'
因此,查資料顯示,需要自己寫一個函數:
import collections
def flatten(x):
result = []
for el in x:
if isinstance(x, collections.Iterable) and not isinstance(el, str):
result.extend(flatten(el))
else:
result.append(el)
return result
print(flatten(["junk",["nested stuff"],[],[[]]]))
