Tôi không thể nói cho bạn biết bao nhiêu lần nó được lặp lại Tôi đang chạy console2 và lịch sử lệnh bị cắt sau 300 dòng của tôi. Tôi có thể in toàn bộ nội dung vào một tệp văn bản nếu cần nhưng tôi nghĩ tôi sẽ hỏi trước. Có ai biết điều này là gì hay làm thế nào để sửa chữa nó?

Theo this post, bạn có thể nâng cấp lên Cryptography 1,7 với pip:

pip install --upgrade pip 
pip install cryptography>=1.7 --upgrade
