In most cases, float and doubleĬomparison gives the same result. A decision tree comparesįeatures to thresholds. It contains integer features with different order Let’s look intoĪn example which always produces discrepencies and some ways Jby Zach How to Fix in Pandas: could not convert string to float One common error you may encounter when using pandas is: ValueError: could not convert string to float: '400. Therefore,Įven a small dx may introduce a huge discrepency. Please report this error to Product Feedback. Owen Harris' Kaggle Something went wrong and this page crashed If the issue persists, it's likely a problem on our side. Trained for a regression is not a continuous function. Titanic survival decision tree: ValueError: could not convert string to float: 'Braund, Mr. However, that’s not the case for every model. \Delta(y) \leqslant \sup_x \left\Vert f'(x)\right\Vert dx.ĭx is the discrepency introduced by a float conversion, That assumption is usually true if the predictionĭy = f'(x) dx. The predictions, the conversion to float introduce smallĭiscrepencies compare to double predictions. ONNX was initiallyĬreated to facilitate the deployment of deep learning modelsĪnd that explains why many converters assume the converted models That’s the most common situation with GPU. This error usually occurs when you attempt to convert a string to a float in pandas, yet the string contains one or more of the following: Spaces. Most models in deep learning use float because Most models in scikit-learn do computation with double, To download the full example code Issues when switching to float # My guess its the readexcel line, where text is being loaded and converted (if possible) to a dataframe.
