Ensure that you activate `debug` mode before using `assert` statements in the Taichi scope:

```python
import taichi as ti
ti.init(arch=ti.cpu, debug=True)

x = ti.field(ti.f32, 128)
x.fill(-1)

@ti.kernel
def do_sqrt_all():
for i in x:
assert x[i] >= 0
assert x[i] >= 0, f"The {i}-th element cannot be negative"
x[i] = ti.sqrt(x[i])

do_sqrt_all()
```

When you are done with debugging, set `debug=False`. Then, the program ignores all `assert` statements in the Taichi scope, which can avoid additional runtime overhead.
