System information

  • Have I written custom code (as opposed to using a stock example script provided in TensorFlow):
import tensorflow as tf

a = tf.Variable(2)
a.assign(5)
assert a.numpy() == 5

# ValueError: Shapes () and (2,) are incompatible
a.assign([1,2])  

# TypeError: assign() got an unexpected keyword argument 'validate_shape'
a.assign([1,2], validate_shape=False)

In this article https://link.springer.com/article/10.1186/1471-2105-8-25 concerns about using gini for feature importance is being raised.

We found that for the original random forest method the variable importance measures are affected by the number of categories and scale of measurement of the predictor variables, which are no direct indicators of the true importance of the variable.

What's the ETA for updating the massively outdated documentation?

Please update all documents that are related building CNTK from source with latest CUDA dependencies that are indicated in CNTK.Common.props and CNTK.Cpp.props.
I tried to build from source, but it's a futile effort.

I was going though the existing enhancement issues again and though it'd be nice to collect ideas for spaCy plugins and related projects. There are always people in the community who are looking for new things to build, so here's some inspiration For existing plugins and projects, check out the spaCy universe.

If you have questions about the projects I suggested,

You can’t perform that action at this time.
