Hello Harsha,
Please drop a mail to us at

I am getting this error “input contains nan, infinity or a value too large for dtype(‘float64’)” when running this code
clf = RandomForestClassifier(n_estimators=10, max_depth=6, n_jobs=1, verbose=2), y_fit)

Can somebody help me with this?

Generally this error occurs when your Input data contains Nan values .You can either solve this error by removing the rows containing the nan values or by filling the nan values with the mean of that particular column.
Here is how you remove the nan values:
here df is your dataframe and by setting inplace as True,you permanently change the Data frame
Here is how you can fill the nan values with mean
