I loaded mat file and I get followed dictionary.

So, I changed this dictionary to Dataframe using X = pd.Dataframe.from_dict(Y)

But, I expect to followed dataframe.

(The single value type whether int or float is not important to me.)

How can change numpy array to single value?

Thanks for your help.

CodePudding user response：

It looks like the elements in your dataframe are lists with a single element. To get rid of that, you can simply use the pandas method explode. So in your case, X = X.explode(['A','B']) for all your columns. If you still struggle having numpy arrays instead of floats, X = X.astype(float) should do the trick.
