Ipython: Reload mendalam akan memunculkan NonImplementedError

Hum, types dan deeprelaod adalah sihir yang cukup gelap. Kami mungkin perlu memasukkan beberapa modul ke daftar hitam.

Apakah Anda ingin mencoba PR?

Apakah Anda ingin mencoba PR?

Maaf, saya tidak tahu apa yang terjadi di sana.

Maaf, saya tidak tahu apa yang terjadi di sana.

Jangan khawatir. Kami akan melihatnya! Terima kasih.

@Carreau , saya masih melihat masalah ini di 6.1.0 meskipun types seharusnya telah dikecualikan secara eksplisit seperti di # 10318 Anda. Ada pemikiran? Versi python saya adalah 3.6.2.

Saya juga melihat ini masih di 6.2.1

Hum, selamat membuka kembali, tetapi saya tidak dapat mereproduksi pada pemasangan baru, jadi saya akan memiliki masalah untuk men-debug:

$ ipython

Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import types

In [2]: from IPython.lib.deepreload import reload

In [3]: reload(types)
Out[3]: <module 'types' from '/Users/bussonniermatthias/anaconda/lib/python3.6/types.py'>

Apakah Anda berdua memiliki traceback yang sama persis?

Contoh yang Anda berikan benar-benar berfungsi dengan baik untuk saya. Namun, saya tidak dapat memuat ulang paket lain (mis. json ):

NotImplementedError: 

Saya pikir kita harus lebih pintar dan otomatis mengecualikan modul yang tidak dapat dimuat ulang secara mendalam dan memperingatkan pengguna bahwa mereka tidak dimuat ulang secara mendalam.

solusi sementara: tambahkan kontrol level dalam ke rekursi. Gunakan kode ini di folder startup, di linux adalah: ~ / .ipython / profile_default / startup /
`` `` dari jenis impor ModuleType
dari autoreload import reload as r

def reload (modul, level = 0):
"" "Muat ulang modul secara rekursif." ""
r (modul)
jika level> 0:
untuk atribut_name di dir (modul):
atribut = getattr (modul, nama_atribut)
jika type (atribut) adalah ModuleType:
reload (atribut, level-1)

Saya baru saja mengalami masalah ini juga saat mencoba menggunakan deepreload.reload

Sama di sini ( NotImplementedError saat memuat ulang types )

Python 3.6.4
IPython 6.4.0
macOS 10.13.2

Saya tidak dapat mereproduksi ini dengan types , tetapi saya dapat mereproduksi ini dengan memuat ulang deepreload itu sendiri.
