用于Numba调试的MacOS上的GDB

Question

根据Numba文档，调试Numba的唯一方法是使用GDB调试器。我试着在我的MacOS上安装它。你知道吗

为了检查所有设置是否正确以及是否具有调试功能，我创建了一个test2.py文件（这是从Numba Docs中的示例1.17.7.1中提取的）：

from numba import njit
@njit(debug=True)
def foo(a):
    b = a + 1
    c = a * 2.34
    d = (a, b, c)
    print(a, b, c, d)

r= foo(123)
print(r)

但是，当我键入：

NUMBA_OPT=1 gdb -q python

我得到以下警告：

warning: `/tmp/lto.o': can't open to read symbols: No such file or directory. (No debugging symbols found in python)

因此，当我执行test2.py脚本时，会得到一个非常大的警告列表：

根据这个question的答案，似乎绑定所有.o文件的临时lto文件没有被保留。你知道吗

还有什么想法吗？你知道吗
