ImportError: No module named matplotlib.pyplot - pomimo, że mam zainstalowanego matplotlib i działa

Question

Cześć. Następujący program działa mi z matplotlib:

import matplotlib.pyplot as plt
import numpy as np


skala = np.linspace(0.,1.,3)
B=[1,5,77]
plt.plot(skala, B)
plt.show()

Wyświetla wykres bez problemu. Ale, gdy próbuję uruchomić coś takiego z terminala:

import matplotlib.pyplot as plt
import numpy as np

from sys import argv

key1 = [340282366920938463463374607431768211455,340282366920938463463374607431768211453,340282366920938463463374607431768211451,340282366920938463463374607431768211449,340282366920938463463374607431768211447,340282366920938463463374607431768211445,340282366920938463463374607431768211443,340282366920938463463374607431768211441,340282366920938463463374607431768211439,340282366920938463463374607431768211437]  # increments
key2 = [240282366920938463463374607431768211455,240282366920938463463374607431768211453,240282366920938463463374607431768211451,240282366920938463463374607431768211449,240282366920938463463374607431768211447,240282366920938463463374607431768211445,240282366920938463463374607431768211443,240282366920938463463374607431768211441,240282366920938463463374607431768211439,240282366920938463463374607431768211437]  # multipliers
r = len(key1)  # nmbr of rounds implied by keys
pt = int(argv[1])  # the plaintext


def round(s, key1, key2):

    s = s + key1
    s = (key2 * s) % 2**128

# here is just XSL-RR-RR mixer (I had to write my own rotr function):

    x=s
    count1 = x >> 122
    x1 = (x ^ (x >> 64)) % (1 << 64)
    low64 = (((1 << (64 - count1)) * ((x1 % (1 << count1)) + (1 << count1))) ^ (1 << 64)) + (x1 >> count1)
    x2 = (x >> 64) % (1 << 64)
    count2 = low64 & 63
    high64 = (((1 << (64 - count2)) * ((x2 % (1 << count2)) + (1 << count2))) ^ (1 << 64)) + (x2 >> count2)
    s = (high64 << 64) | low64

    return s


def encrypt(pt, key1, key2, r):
    ct = pt
    for i in range(r):
        ct = round(ct, key1[i], key2[i])
    return ct

n=(encrypt(pt, key1, key2, r)) % 32

skala = np.linspace(0.,1.,3)
B=[1,5,n]
plt.plot(skala, B)
plt.show()

To dostaję błąd:

Traceback (most recent call last):
  File "C:\Users\omnia\PycharmProjects\Collatz\Chwilowy.py", line 1, in <module>
    import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib'
 

I to już przy wczytywaniu biblioteki. O co chodzi?

Answer 1

ModuleNotFoundError: Brak modułu o nazwie „matplotlib”

zainstaluj pip

https://pypi.org/project/pip/

później

pip install matplotlib

Jeśli to nie pomoże to spróbuj =>

pip uninstall matplotlib
python3 -m pip install matplotlib

Powodzenia i Pozdrawiam Serdecznie
