주피터 연구실에서는 dill.juffter_del_del이 작동하지 않을 것이다

스파이더 대신 주피터 연구실에서 일을 시작하고 싶은데 문제가 있어요. 작업영역에 변수를 저장할 수 없습니다.

주피터 랩을 사용하여 다음과 같은 코드를 실행하려고 합니다:

import dill
import pandas as pd
import numpy as np

df = pd.DataFrame({'A': np.arange(1,300), 'B': np.arange(2,301)})
STRIN = 'A'
aa = 34

dill.dump_session('filename.p')

그리고 다음과 같은 오류가 발생합니다:

TypeError: no default __reduce__ due to non-trivial __cinit__

그리고 전체 추적은 다음과 같습니다:

이걸 고치려면 어떻게 해야 하나요?

감사해요!

딜이 zmq 소켓을 피클화하려고 하는 것처럼 보이는데, 이는 주피터 환경이 당신의 세션에 연결되기 때문에 발생하고 있다. 예 및 를 참조하십시오.

나는 네가 이것을 목성 밖에서 하려고 한다면 그것이 효과가 있을 것이라고 장담한다.

나는 딜이 목성 안에서 작동하고 있다는 것을 감지하고 이것을 피하기 위해 아마도 더 많은 것을 할 수 있을 것이라고 생각하지만 현재로서는 그것이 작동하는 방식이 아닌 것 같다.

IPython 및 ipykernel 패키지에 소켓 개체를 직렬화하는 데 문제가 있습니다. 이 물체들은 걸러져야 한다. 사전을 재설정하고 원하는 지속성을 얻으려면 다음 코드를 실행하십시오:

from dill._dill import register
from dill._dill import save_module_dict

@register(dict)
def snb_save_module_dict(pickler, obj):
  keys=list(obj.keys())
  for k in keys:
    if type(obj[k]).__module__.startswith("ipykernel.") or type(obj[k]).__module__.startswith("IPython."):
      obj.pop(k,None)
    else:
      pass
      #print(k,obj[k])
  save_module_dict(pickler, obj)
