I use the below code and it report error, This is a very simple example and should not report error as expected.
import numpy as np
import torch as th
# Assuming tt is some data (example as list)
tt = [1, 2, 3, 4, 5] # Example data
# Check if tt is a NumPy array, and convert if necessary
if not isinstance(tt, np.ndarray):
tt = np.array(tt)
# Now, convert tt to a PyTorch tensor
tensor_tt = th.from_numpy(tt)
print(tensor_tt)
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
Cell In[26], line 12
9 tt = np.array(tt)
11 # Now, convert tt to a PyTorch tensor
---> 12 tensor_tt = th.from_numpy(tt)
13 print(tensor_tt)
TypeError: expected np.ndarray (got numpy.ndarray)

I try to convert np.array data to tensor in torch; The reporting error is confusing; I do not know whether there is conflicting in the package versions.
When I downgrade the numpy it still report the same error:
import numpy as np
import torch
print(torch.__version__)
print(np.__version__)
x = np.array([[1, 2, 3, 4], [5, 6, 7, 8]], dtype=np.float32)
y = torch.from_numpy(x)
2.4.1
1.26.0

"name": "TypeError",

This is a known error, you need to uninstall numpy by:
pip uninstall numpy
then install "numpy<1.26.4" afresh.
pip install "numpy<1.26.4"
https://github.com/huggingface/diffusers/issues/9069#issuecomment-2267596351
https://github.com/pytorch/pytorch/issues/135836#issuecomment-2347209235

After a number of trials I figure out why there is problem.
Note that there are two numpy versions numpy (1.26.4) and numpy-base (2.1.2) in the installation. If you uninstall numpy (1.26.4) and then reinstall by conda install numpy==1.26.0, your error will remain; what you need to do is to pip uninstall numpy again to ensure the version 2.1.2 is also removed.
