Python - AttributeError: 'numpy.ndarray' object has no attribute 'to'

It would be nice to see your train_generator code for clarity, but it does not seem to be a torch DataLoader. In this case, you should probably convert your arrays to tensors manually. There are several ways to do so:

torch.from_numpy(numpy_array) - for numpy arrays;
torch.as_tensor(list) - for common lists and tuples;
torch.tensor(array) should also work but the above ways will avoid copying the data when possible.

if you need to flatten you can directly use flatten() on numpy.ndarray object

X = X.flatten()

Link to doc: https://numpy.org/doc/stable/reference/generated/numpy.ndarray.flatten.html

2 of 2

DO NOT VOTE UP RESPONSE MAIN WORK DONE BY @wayne above:

Did you run print(type(X)) on X prior to that line that gave an error? Given you got an error of AttributeError: 'numpy.ndarray' object has no attribute 'to_numpy', X appears to already be numpy object. Also, I don't think the to_numpy comes from numpy. Pandas has one. Polars has one. This drops us in the end of the problem and so we cannot provide much help without more code upstream.

solution

reload data set.

df = pd.read_csv(file_name, header=0)

[str(i) for i in ([["CPU_frequency"]])]

code above resolves.

adv_ex is already a numpy array, so you can’t call .numpy() again on it (which is a tensor method). Store adv_ex as a tensor or avoid calling numpy on it: adv_ex = perturbed_data.squeeze().detach().cpu() adv_examples.append( (init_pred.item(), final_pred.item(), adv_ex) )

r/learnpython on Reddit: Error creating numpy v-stack, 'AttributeError: 'numpy.ndarray' object has no attribute 'np'

May 4, 2021 -

Hi,

I'm trying to create a numpy v-stack and creating 3 np.array's for it, by filling them with a loop:

I get the error: 'AttributeError: 'numpy.ndarray' object has no attribute 'np' . I think I'm using the wrong notation to append to the empty arrays:

neighbor_id = [id_ for id_ in range(1, n_obs) if id_ != user_id]

neighbor_id_arr = np.array(neighbor_id)

similarity = np.array([])

num_interactions = np.array([])

# get similarity and num_interactions

for id_ in neighbor_id:

similarity.np.append(np.dot(user_item.loc[user_id],user_item.loc[id_])) #The issue is here, I think

num_interactions.np.append(user_interactions.loc[id_])

c = numpy.vstack((neighbor_id_arr, similarity,num_interactions))

Thanks!
James

I think I'm using the wrong notation to append to the empty arrays: The best way to find out is to read the documentation https://numpy.org/doc/stable/reference/generated/numpy.append.html And yes you are. Numpy arrays don't have an append method, it's a function from the library. And there is no such thing as object.library.function(...) which is what you are doing here similarity.np.append(...) num_interactions.np.append(...) It should be similarity = np.append(similarity, values_to_append) num_interactions = np.append(num_interactions, values_to_append) And should avoid appending data to a numpy array. I'm almost sure there is much better alternative. But since you didn't explain what you are trying to do, I can't help you with that.

2 of 2

I think you want to use "np.append(arr, values)" instead of arr.np.append(values)". https://numpy.org/doc/stable/reference/generated/numpy.append.html

Hello,

Linked is the screenshot of the two error messages I keep recieving as well as the code leading up to it. I'm trying to run an uplift on a classification tree. Any help is appreciated, I am still fairly new to python. Thank you!!

You should not be accessing dataframe columns with the dot notation. This is one of the reasons why. Use uplift_df['MESSAGE_A'].

2 of 5

I'm not familiar with your use case, but are you expecting MESSAGE_A to exist for any particular reason? I can't find documentation of it. Can you link to the tutorial or reference page that told you it exists?

Top answer

You are using the right method but in a wrong way :)

nan_to_num is a method of numpy module, not numpy.ndarray. So instead of calling nan_to_num on you data, call it on numpy module giving your data as a paramter:

import numpy as np
data = np.array([1,2,3,np.nan,np.nan,5])
data_without_nan = np.nan_to_num(data)

prints:

array([1., 2., 3., 0., 0., 5.])

In your example:

import numpy as np
val = np.nan_to_num(setTo.ravel())

Why do I get “numpy.ndarray object has no attribute append error”? - Quora

This error occurs because numpy.ndarray objects do not implement the list method append — numpy arrays have a fixed size and their API differs from Python lists. Calling arr.append(...) raises AttributeError.

Yes, you must change your individual type from list to numpy.ndarray (that would be the same thing if you would like to inherit from, say, array.array).
