No such file or directory: 'snakeviz'

[ifishlin]

Hi, when I run the script in 01-map.ipynb, and I always got this error msg.

I have installed snakeviz 0.4.1, any clues? thanks

FileNotFoundError: [Errno 2] No such file or directory: 'snakeviz'

%%snakeviz

for fn in filenames:
    print(fn)
    with open(fn) as f:
        data = [json.loads(line) for line in f]
        
    df = pd.DataFrame(data)
    
    out_filename = fn[:-5] + '.h5'
    df.to_hdf(out_filename, '/data')
