### Problem: Jupyter (Sage) with Numba and pypy

I install it by:

```
pip3 install numba
```

How to use and import numba, pypy in sage.

I get:

```
ModuleNotFoundError: No module named 'numba'
```

when I run the following code ~~(https://numba.pydata.org/numba-doc/latest/user/5minguide.html):~~(from
https://numba.pydata.org/numba-doc/latest/user/5minguide.html )

```
from numba import jit import numpy as np import time
x = np.arange(100).reshape(10, 10)
@jit(nopython=True) def go_fast(a): # Function is compiled and runs in machine code
trace = 0
for i in range(a.shape[0]):
trace += np.tanh(a[i, i])
return a + trace
start = time.time() go_fast(x) end = time.time() print("Elapsed (with compilation) = %s" % (end - start))
start = time.time() go_fast(x) end = time.time() print("Elapsed (after compilation) = %s" % (end - start))
```
