Мне нужен словарь переменных списка для jitclass. Следующее сообщение выдает ошибку.
Я попробовал 10 разных способов, но не помогло. Все значения словаря имеют одинаковую длину списка.
import numpy as np
import pandas as pd
from numba.experimental import jitclass
from numba import types
import os
os.environ['NUMBA_VERBOSE'] = '1'
spec = [
('data', types.Array(types.Record, 1, layout='C'))
]
@jitclass(spec)
class Test:
def __init__(self, data):
self.data = data
def loop(self):
v = self.data['v']
v2 = self.data['v2']
print("Inside loop:")
print("v:", v)
print("v2:", v2)
data = [[1, 2, 3], [1.0, 2.0, 3.0]]
# Define the structured array dtype
dtype = np.dtype([
('v', np.int64),
('v2', np.float64)
])
# Create the structured array
data_array = np.array(data, dtype=dtype)
print("Original data array:")
print(data_array)
# Create an instance of the Test class
test = Test(data_array)
test.loop()
