Code doesn't display the widget on Jupyter Notebook

[Winghin2517]

I'm trying to display the clustergrammer widget in my jupyter notebook but it just doesn't seem to work.

I took the example code off this page and ran it on my jupyter notebook on my mac but it gives me empty results :https://github.com/MaayanLab/clustergrammer-widget/blob/master/Running_clustergrammer_widget.ipynb

As you can see, the integer slider works properly, so therefore it cannot be the widgetsnbextension that is a problem.

These are my dependencies from running a conda list:

widgetsnbextension 3.0.2 py35_0 conda-forge
ipywidgets 7.0.0 py35_0 conda-forge
clustergrammer-widget 1.13.0

I ran this:

jupyter nbextension enable --py --sys-prefix clustergrammer_widget

and this was the result:

Enabling notebook extension clustergrammer_widget/extension...
- Validating: OK

However, when I viewed the code off the jupyter nbviewer website, it works perfectly:

http://nbviewer.jupyter.org/github/MaayanLab/clustergrammer-widget/blob/11b36f36b613c2ec2081415c3f81b2d3fcf9507f/Python%203.5%20test.ipynb

Can you please tell me what I'm doing wrong here?

First, check whether the visualization object, net.viz, is being populated after clustering

net.viz is initialized as

{'cat_colors': {'col': {}, 'row': {}}, 'row_nodes': [], 'col_nodes': [], 'links': [], 'mat': []}

and clustering should populate this object. If net.viz is not populated after running net.cluster() then something has gone wrong with your clustering.

The problem might also be that you need to restart Jupyter notebook after enabling the extension.

Finally, we just released version 1.13.1. You can try upgrading to this version using

pip install --upgrade clustergrammer_widget

Let us know if this helped.

Best,
Nick

Hello,

I am facing the same issue. I have taken all the necessary steps previously mentioned. Successfull enabled the extension, upgrading of widget and restarting the notebook after upgrading and here is my net.viz :
{'cat_colors': {'col': {}, 'row': {}}, 'col_nodes': [{'clust': 2, 'group': [1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 30, 'name': 'CL53', 'rank': 26, 'rankvar': 26}, {'clust': 12, 'group': [13.0, 10.0, 6.0, 3.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 29, 'name': 'CL253', 'rank': 1, 'rankvar': 1}, {'clust': 8, 'group': [7.0, 6.0, 5.0, 3.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 28, 'name': 'CL219', 'rank': 4, 'rankvar': 4}, {'clust': 26, 'group': [23.0, 13.0, 7.0, 3.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 27, 'name': 'CL214', 'rank': 29, 'rankvar': 27}, {'clust': 10, 'group': [9.0, 7.0, 5.0, 3.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 26, 'name': 'CL172', 'rank': 18, 'rankvar': 16}, {'clust': 4, 'group': [6.0, 5.0, 4.0, 2.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 25, 'name': 'CL213', 'rank': 13, 'rankvar': 13}, {'clust': 24, 'group': [26.0, 13.0, 7.0, 3.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 24, 'name': 'CL156', 'rank': 21, 'rankvar': 23}, {'clust': 9, 'group': [8.0, 6.0, 5.0, 3.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0], 'ini': 23, 'name': 'CL167', 'rank': 2, 'rankvar': 2}, .......
List is very very long... But still I am not getting any output from net.widget. Any suggestions please. Thanks.

Hi @vivekruhela, what kind of output are you getting when you run net.widget? Is the Jupyter notebook displaying an error?

[vivekruhela]

Sorry for late reply. Problem is solved. Now I am getting the output from net.widget(). The only problem I am facing is the clustergrammer is not fit into the browser. I have to reset the zoom level to 50 or 60% to make it visible completely. Is there any way to get output perfectly fit in browser window. Thanks.

@vivekruhela I'm glad that is working now. Currently we do not support resizing the heatmap, but this is a feature we are working on for this and the new Clustergrammer2 WebGL widget. We can keep you posted

Hi, I get the same problems as described above on python 3.7 with pandas-0.24.2; notebook-kernel 5.1.1; ipywidgets 7.4.2.

It only works with the downloaded two-cats example notebook. In a fresh notebook running the same cells the widget does not appear; 'net.viz' sometimes gives below (expected?) results sometimes not.

Using the "General Purpose Pandas DataFrame Viewer" approach (loading a dataframe in the example with df2=pd.read_csv('../Clustergrammer/data/rc_two_cats.txt', sep='\t')
gives a fault (and net.viz remains empty) which did not occur with my own file (refreshing the kernel does not help):
