编程语言mojo报错：error: cannot call function that may raise in a context that cannot raise

代码：

from python import Python



fn main():
# fn main() raises:
    # This is equivalent to Python's `import numpy as np`
    let np = Python.import_module("numpy")
    let a = np.array([1, 2, 3])
    print(a)

 

运行报错：

================================================

 

 

mojo是一个新的AI编程语言，其中一个特点就是可以很好的和python融合，上面的代码则是在mojo中调用python，报错，解决方案：

 这里修改后的代码：

from python import Python



fn main() raises:
    # This is equivalent to Python's `import numpy as np`
    let np = Python.import_module("numpy")
    let a = np.array([1, 2, 3])
    print(a)
