The error keeps saying:
Downloading data from https://storage.googleapis.com/tensorflow/tf-keras-datasets/mnist.npz 16384/11490434 [..............................] - ETA: 10s
and keeps doing this continuously, The code I wrote is this:
import tensorflow as tf
(x_train, y_train), (x_test, y_test)= tf.datasets.mnist.load_data()
print(x_train[0])
I am trying to print the array of an image using this command, I know I can do it other ways, but I am trying to use "keras.datasets.mnist.load_data()" specifically. What does this error mean?
My tensorflow version is 2.6.1 and python is 3.9.7
The error is shown in the image:
Ok I figured out what went wrong, it is because the file was not downloading permanently in its folder using python's IDLE. When I had used Jupyter Notebook somehow it installed it permanently. In other words, after python's IDLE downloads the file, the downloading phase will stop and the file will go away and python will continuously keep trying to look for it inorder to completely execute the command. Since it could not, you can say python was chasing its tail.
If you were to manually download it and use the same command, python's IDLE will be able to use it. However if you messed with the manually downloaded file by changing the way the file should be opened and you use another command such as mnist.load_data("mnist"), you will have to find that file somehow like how I did, by downloading anaconda and using jupyter Notebook or something similar.
The reason why python's IDLE is doing that I have no clue, but if you can somehow find a way to install it permanently the program will work.

I am encoutering import errors, but only when running my python scripts from cmd or windows task scheduler (effectively the same issue I assume). I have researched answers already and attempted various solutions (detailed below), but nothing has worked yet. I need to understand the problem in any case so that I can manage anything like it in the future.
Here is the issue:
Windows 10. Anaconda Python 3.9.7. Virtual enviromnent.
I have a script that works fine if I open an anaconda prompt, activate the virtual environment and run it.
However, this is where the fun starts. If I try to run the script from the non-anaconda cmd prompt deploying the commands: "C:\Users\user\anaconda3\envs\venv\python.exe" "C:\Users\user\scripts\script.py" if get the following error:
ImportError: DLL load failed while importing etree: The specified module could not be found.
Traceback includes:
"C:\Users\user\anaconda3\envs\venv\lib\site-packages\lxml\html\__init__.py", line 53, in <module>
from ..import etree
This is not as simple as one specific module not being installed, because of course running the script from within the anaconda prompt and the virtual environment works. Similar also happens when I run other scripts. Other errors I have seen include, for example:
ImportError: DLL load failed while importing _imaging: The specified module could not be found.
Traceback includes:
"C:\Users\user\anaconda3\envs\venv\lib\site-packages\PIL\Image.py", line 114, in <module>
from . import _imaging as core
Also, I think this may be somehow related. Importing numpy (1.22.3) from within the python interpreter in the virtual environment works fine, but when I try to run a test script that imports numpy it fails both from anaconda and the cmd with the following error:
ImportError: cannot import name SystemRandom
The oveall issue was noted originally when trying to run various scripts from Windows Task Scheduler with the path to python "C:\Users\user\anaconda3\envs\venv\python.exe" entered as the Program/script and the script "script.py" entered as an argument. The above errors were produced, then reproduced by running the scripts from a non-anaconda cmd.
I am looking to understand what is happening here and for a solution that can get the scripts running from the virtual enviroment from Windows Task Scheduler effectively.
Update:
I have uninstalled and reinstalled numpy (and pandas) using conda. This has left the venv with numpy==1.20.3 (and pandas=1.4.2). On attempting to re-run one of the scripts, it runs fine from within the venv in anaconda, but produces the following error when attempting to run from cmd or from within Windows Task Scheduler as above:
ImportError: Unable to import required dependencies:
numpy:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions faled. This error can happen for many reasons, often due to issues with your setup or how NumPy was installed.
We have complied some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "C:\Users\user\anaconda3\envs\venv\python.exe"
* The NumPy version is "1.20.3"
and make sure that they are the versions you expect.
Please carefull study the documentation linked above for further help.
Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.
I have looked into the solutions suggested, but am still completely at a loss, especially as to why the script runs from the venv in one place, but NOT the other.
I am using the book Python Crash Course as a textbook. I was doing pretty well until I tried to use the Matplotlib library. The book gave the following command to install the library:
python -m pip install --user matplotlib
I entered this in the terminal window in Pycharm (the IDE I am using). It appeared to work, in that I got a series of messages indicating that files were being downloaded and installed on my computer. However when I attempted to import matplotlib.pyplot into an example piece of code I was trying to write, I got a ModuleNotFoundError: No module named 'matplotlib'
I assumed that the downloaded module went to the wrong directory, so I searched my hard drive to find a file or folder named matplotlib. I found several folders in different locations, but when I tried copying them into folders where I knew Pycharm could find it, it didn't seem to help. Can someone please clue me in to how I can use this module.
I am using windows 10 on an MS Surface 6.
I generally like to make my python programs in a text editor and then run them after they are complete instead of line arguments. Thus, I save those .py files on a convenient folder location instead of Python program files.
I then run my .py file using Command Prompt. However it has not worked for the Biopython library as import Bio gives back a Traceback No module named 'Bio'. However, using line arguments directly on python shows it is installed.
I have never had this issue with Python in general and other downloaded libraries (import numpy for example works fine). How do I make the files available to be open from any location?? Or how do I provide the path in import?
To clarify and add:
1) I use Python from Windows 10
2) I downloaded and installed Python(3.7) from python.com
3) I downloaded Biopython using pip (and all other libraries I downloaded)
4) I also tried it on Jupyter notebook and also does not work to import Bio, whereas Import numpy does.
Thanks!
I installed the word cloud library in python to use wordcloud. I am able to successfully use it in all editors like sublime, etc but when I am trying to use it in Jupyter notebook then it is giving me error:
DLL load failed: The specified module could not be found
I have been trying to solve this issue from last 2 days but not getting success. I would appreciate any kind of help.
I too faced this issue.
the problem was when wordcloud is installed it gets python modules and stores in
**C:\Python27\Lib\site-packages** folder (in my case this is the python executable path this may vary for you) so when you import from jupyter it tries to find it in this path , but wordcloud creates one more folder with same name and downloads all wordcloud module in side this , this is one more level in directory so jupyter is unable to find. so the hack what i did is copied all modules from inner wordclod folder to one level outside i.e
copy all from C:\Python27\Lib\site-packages\wordcloud\wordcloud ->
C:\Python27\Lib\site-packages\wordcloud
so this made the trick and no more error.
i am trying to create an executable from my python script. My script runs fine, but after freezing it, starting the .exe gives me the following error:
http://www.bild.me/bild.php?file=4663406scipyerror.png
I am using Python 3.2.3, Scipy 0.12.0b1, Numpy 1.7.0 and Matplotlib 1.2.0 (all 32bit).
Any ideas/hints on how to solve this? My guess is i have to include something manually in my freezing script, but i am running out of guesses :-(
I got it finally to work, but I am very unsatisfied with my solution:
1) copy _odepack.pyd and odepack.py from the SciPy package to my program folder
2) in odepack.py change from . import _odepack to import _odepack (otherwise ValueError: Attempted relative import in non-package is raised)
3) in my main change from scipy.integrate import odeint to from odepack import odeint
Now it is working as expected and after using cx_freeze it is still working.
Still got no idea why it would not work before :-(
Thanks ThomasK for pushing me in the right direction though :-)
I finally got around this vode-problem by specifying "scipy.integrate.vode" as an include in the cx setup-file. This resulted in a file "scipy.integrate.vode.pyd" to end up in the build folder. I am using SciPy 0.11, Python 3.2.3 and the latest cx on Windows.
But adding such a "scipy.integrate.vode" file manually to the build folder would not fix the problem for me either, even though such manual-include-fixes were needed for many other .pyd files cx could not find either (and whereby the above setup.py include-solution would not work instead)...
Thanks for sharing your distress and wisdom, would not have managed to freeze my program otherwize...
