Jak ją zainstalować? Instrukcje do poprzedniej mam stąd:
https://www.pcg-random.org/posts/how-to-test-with-practrand.html
Działanie samego programu w konsoli również kończy się szybko. Po wypisaniu kilku krzaków, dostaję błąd:
Traceback (most recent call last):
File "Collatzgenerator01.py", line 63, in <module>
sys.stdout.buffer.write(binary)
OSError: [Errno 5] Input/output error
Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>
OSError: [Errno 5] Input/output error
Takiego zatrzymania nie ma w PyCharmie. Co sugeruje, że program stwarza z jakichś powodów problem dla konsoli. Coś z przepełnieniem pamięci, z tego co czytam. Korzystam z konsoli Linuxowej (Ubuntu) na Windowsa. Może tu jest problem. Rozwiązania znalezione w sieci jak na razie nie działają.
