ImportError: cannot import name 'FeedHandler'

[Promptineer]

Hi everyone! I have just recently found cryptofeed and am beyond excited to bring some ideas I had to life. However, I am finding myself stumped by a stupid import error. I'm not sure if it is due to how I installed the cryptofeed module, or something I am doing terribly wrong. I tried to find a fix on StackOverflow, but wasn't able to find anything that seemed relevant :(

Here's the sample code:

from cryptofeed import FeedHandler
from cryptofeed.exchanges import Coinbase

def nbbo_update(symbol, bid, bid_size, ask, ask_size, bid_feed, ask_feed):
    print(
        f'Pair: {symbol} ' +
        f'Bid Price: {bid:.2f} ' +
        f'Bid Size: {bid_size:.6f} ' +
        f'Bid Feed: {bid_feed} ' +
        f'Ask Price: {ask:.2f} ' +
        f'Ask Size: {ask_size:.6f} ' +
        f'Ask Feed: {ask_feed}'
    )

fh = FeedHandler()
fh.add_nbbo([Coinbase], ['BTC-USD'], nbbo_update)
fh.run()

and my output:

Traceback (most recent call last): File "/home/cannon/projects/movingavg/cryptofeed.py", line 1 in <module> from cryptofeed import FeedHandler File "/home/cannon/projects/movingavg/cryptofeed.py", line 1 in <module> from cryptofeed import FeedHandler ImportError: cannot import name 'FeedHandler

I've tried from cryptofeed import * but then I am given a NameError when FeedHandler is referenced. I have no idea why FeedHandler is not being imported? I installed cryptofeed via pip if that helps at all. Sorry for posting something as simple as an import error, but I am so eager to use cryptofeed and didn't know what else to do.

What version of python are you using? Also, that code is incomplete, you'll need to import those exchanges you are referencing as well. There is a lot of sample/demo code in examples/

oh, i see the issue, you named your file the same name as the package/module, so that wont work. Rename your python file something other than cryptofeed.

I'm using python 3.6. Oops that was my mistake, I posted the wrong code earlier. I pasted sample code from my OS, thinking it was the code from my virtual machine. Oh wow! Boy do I feel dumb... Thank you so much for the help! Hopefully this interaction can save some other newbie some time as well haha

you may or may not have issues depending on what you try and do. Cryptofeed requires 3.7+

Ahh I see, I will go ahead and update everything then. Thanks again!
