Saya ingin menggunakan lateks untuk label gambar tetapi saya mendapatkan kesalahan
RuntimeError: LaTeX tidak dapat memproses string berikut: b'lp'
Berikut adalah laporan lengkap yang dihasilkan oleh LaTeX: < br/> dan itu saja (saya tidak melihat laporan apa pun)
Sunting : Inilah seluruh kesalahan yang saya peroleh:

Here is the full report generated by LaTeX:
Ini kode saya:
import numpy as np
from matplotlib import rc
import matplotlib.pyplot as plt
plt.close('all')
rc('text', usetex = True)
mu = np.linspace(0,10,100)
eta = mu**2
fig, ax = plt.subplots()
ax.plot(mu,eta,label= r'$\eta (\mu)$')
ax.set_title('Test')
ax.legend()
- Saya menginstal MiKTeX, menambahkannya ke variabel lingkungan sesuai dengan https://docs.alfresco.com/4.2/tasks/fot-addpath.html.
- Saya memeriksa paket MiKTeX, di mana saya menemukan "miktex-dvipng-bin-x64-2.9" di kategori "\MiKTeX excecutables". Saya menyimpulkan saya punya dvipng.
- Saya mengunduh Ghostcript, yang juga saya tambahkan ke variabel lingkungan.
- Saya mencoba mengkompilasi skrip lateks ke pdf menggunakan texworks, dan berfungsi dengan baik, dari apa yang saya simpulkan, LaTeX diinstal dengan benar.
- Dari https://matplotlib.org/1.4.1/users/usetex.html, hanya ini yang seharusnya saya perlukan...
- Saya mencoba menghapus direktori .matplotlib/tex.cache saya
- Saya mencoba menulis
import matplotlib as mpl
mpl.rcParams['text.usetex']=True
alih-alih
from matplotlib import rc
rc('text', usetex = True)
tapi hasilnya sama.
- Beralih
rc('text', usetex = True)
to
rc('text', usetex = False)
mencegah kesalahan, tetapi label saya tidak ditulis dengan lateks...
Setelah banyak googling, saya kekurangan ide. Adakah yang bisa membantu saya?
Konfigurasi saya adalah:
- Python 3.6 (Saya menjalankan kode saya di spyder)
- MiKTeX 2.9
- Ghostscript 9.50
- Windows 10
- Edit : matplotlib 2.0. 2
Sunting: memutakhirkan ke matplotlib 3.1.1, saya mendapatkan kesalahan berikut:
