GausianNB: Could not convert string to float: 'Thu Apr 16 23:58:58 2015' 5 Does increasing the n_estimators parameter in decision trees always increase accuracy Hi @adityashrm21,. Specifically, it splits out columns of categorical data into sets of boolean columns, one new column for each unique value in each input column. In that case I assume that you are able to run your random forest. Multiple Left Joins in MS Access using sub-queries. All columns of the dataframe are float and the output y is also float. (mydata is a 2d array of string datatype): You can’t pass str to your model fit() method. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … String having non-numerical Here's some code I looked at (I don't believe I used it), to obtain the iris data, from scikit-learn's website: from sklearn import datasets iris = datasets . However OneHotEncoder does not support to fit_transform() of string. works well, but in that case because the str does not have numerical meaning for the classifier. Internally, it will be converted to dtype=np.float32 and if a sparse matrix is provided to a sparse csc_matrix. For example, ValueError: could not convert string to float: 'path_1' Here's a minimal example producing the error: import pandas as pd from imblearn.under_sampling import RandomUnderSampler from imblearn import FunctionSampler # create one dimensional feature and label arrays X and y # X has to be converted to numpy array and then reshaped. After finishing this article, you will be equipped with the basic techniques of data pre-processing and their in-depth understanding. Hi @adityashrm21,. Status: More Info Needed. OneHotEncoder does not work directly from Categorical values, you will get something like this: ValueError: could not convert string to float: 'bZkvyxLkBI' One way to work this out is to use LabelEncoder(). code snippet # convert X into dataframe X_pd = pd.DataFrame(data=X) # replace all instances of URC with 0 X_replace = X_pd.replace(' ',0, regex=True) # convert it back to numpy array X_np = X_replace.values # set the object type as float X_fa = X_np.astype(float) Obviously this is not possible. load_iris () Mustafa Başaran Required fields are marked *. The type of Y in variable explorer is object and if execute . How to add a custom column which is not present in table in active admin in rails? [duplicate].

ValueError: could not convert string to float: id Somewhere in your text file, a line has the word id in it, which can’t really be converted to a number. Below is an example when dealing with this kind of problem: from sklearn.tree import DecisionTreeClassifier clf = DecisionTreeClassifier() clf.fit(X, y) You get an error: ValueError: could not convert string to float: 'sunny' So definitely, you need to convert … Please, do help me. In that case I assume that you are able to run your random forest. The training input samples. Just remove your string column and pass that column in dummy variable function. Then you are able to transfer by OneHotEncoder as you wish. type(Y) i get numpy.ndarray There are many more options for pre-processing which we’ll explore. Then you are able to transfer by OneHotEncoder as you wish. Follow asked yesterday.
