我这里的测试代码：
python -c "import magenta"
出现错误：
/Users/ghj1976/opt/anaconda3/envs/magenta/lib/python3.7/site-packages/librosa/util/decorators.py:9: NumbaDeprecationWarning: An import was requested from a module that has moved location.
Import requested from: 'numba.decorators', please update to use 'numba.core.decorators' or pin to Numba version 0.48.0. This alias will not be present in Numba version 0.50.0.
from numba.decorators import jit as optional_jit

Import of 'jit' requested from: 'numba.decorators', please update to use 'numba.core.decorators' or pin to Numba version 0.48.0. This alias will not be present in Numba version 0.50.0.
from numba.decorators import jit as optional_jit
修正
pip install numba==0.48.0
再次执行
python -c "import magenta"
就没有上面错误了。
这里不能用下面命令升级到最新版本，是因为这个库内部代码我们控制不了。
pip install numba --upgrade
只能回退到一个之前的版本。
