Using .values on a pandas dataframe gives you a numpy array. This will not contain column names and such. You do this when setting X like this:
X = dataset[['Read?', 'x1', .. ,'x47']].values
But then you try to get the column names from X (which it does not have) by writing X.columns here:
coeff_df = pd.DataFrame(regressor.coef_, X.columns, columns=['Coefficient'])
So store your column names in a variable or input them again, like this:
coeff_df = pd.DataFrame(regressor.coef_, ['Read?', 'x1', .. ,'x47'], columns=['Coefficient'])

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.

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

Using .values on a pandas dataframe gives you a numpy array. This will not contain column names and such. You do this when setting X like this:
X = dataset[['Read?', 'x1', .. ,'x47']].values
But then you try to get the column names from X (which it does not have) by writing X.columns here:
coeff_df = pd.DataFrame(regressor.coef_, X.columns, columns=['Coefficient'])
So store your column names in a variable or input them again, like this:

[rllib] "AttributeError: 'numpy.ndarray' object has no attribute 'items'" on certain turn-based MultiAgentEnvs with Dict obs space. · Issue #17706 · ray-project/ray
August 10, 2021 - I suspect that this error can probably be reproduced with any multi-agent environment that has a Dict observation space (i.e. one with "action_mask" and "observation" keys per agent) since the error is being thrown in the DictFlatteningPreprocessor.

It takes a dict as the second argument not an array:
From the docs:
mdict : dict
Dictionary from which to save matfile variables.
I am not overly familiar but I imagine you pass the name as the key and the array as the value, something like:
sio.savemat('final.mat',{"foo":temp})

I solved this issue as follow:
from scipy.io import savemat
import numpy as np
num= np.arange(20)
mymat={'num':num}
savemat('mymat.mat', mymat)

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) )

Thanks!. My bad, I haven’t noticed that it is already called.

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

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?
