outputs: the Gradio component(s) to use for the output. The number of components should match the number of return values from your function. Thefnargument is very flexible -- you can passanyPython function that you want to wrap with a UI. In the example above, we saw a relatively simp...
The raw prediction result is 0.79, which is higher than 0.5, so the output is 1. The network made a correct prediction. Now try it with another input vector, np.array([2, 1.5]). The correct result for this input is 0. You’ll only need to change the input_vector variable since al...

) print(msg) print('Prediction = ' + str(output)) 最后,我们在评论上调用predict()来做出预测: predict("The film was good") 这将产生以下输出: 图5.20 –正值上的预测字符串 我们还尝试对负值使用predict(): predict("It was not good") 结果为以下输出: 图5.21 –负值上的预测字符串 现在,我...
Output: We can also use Seaborn library to create pairplots of all features in the dataset against each other. To use Seaborn, we need to import Seaborn library, first. Let’s see how it is done and how to create a Seaborn pairplot. Input: import seaborn as sns<br> sns.set(style="...
