dtale.show() not working in macos

[LmYjQ]

My dtale version is 2.15.2.
In jupyter notebook

I also tried d.open_browser()

Thanks for help.

@LmYjQ I was able to run jupyter notebook on Python3.8 with D-Tale 2.15.2 installed with no issue on my macbook. Depending on your browser, could you open "Developer Toolbar" and show the network tab before you call dtale.show? This way we can see what might be happening. Maybe its a firewall thing

@aschonfeld I'm not sure how to check the firewall. Are these messages useful to you?

[aschonfeld]

Hmm, yea that doesn't tell me much other than the fact that your browser can't access the flask process for D-Tale. Can you run dtale.instances() in another cell in your notebook just to make sure that D-Tale in creating an instance for your dataframe?

Another thing I'd like you to try would be opening a python console from your command line. So do the following:

• open a terminal
• activate your virtual environment
• execute python
• run the following code snippet

import dtale
import pandas as pd

dtale.show(pd.DataFrame([1,2,3]))

• this should spit out a URL that you can paste into a browser and should display that dataframe

I'm just trying to see if this is an issue with jupyter or with your machine in general. Thanks

D-Tale instance did created.

python terminal

The Chinese "bogon 未发送任何数据" means bogon didn't send any data. Can I check the data that should be sent?

+1 I get the same issue, Macbook Pro M1 pro, same as "XXX 未发送任何数据" , which means XXX didn't send any data

[aschonfeld]

Can you try hitting the URL http://0.0.0.0:40001? I bet its an issue with the computer name that macos is returning

[Fanghanmo2412]

It works, or you can put your localhost IP with your mac name in /etc/hosts, like this:
127.0.0.1 bogon
there is a space between url and mac name, and it works
@LmYjQ

[aschonfeld]

Ok if that does work then you can fix the behavior by using the hostname parameter. For example:

import dtale
import pandas as pd

dtale.show(pd.DataFrame([1,2,3,4,5]), hostname='127.0.0.1')
