ImportError: No module named 'dask.dataframe';

Question

I'm trying to run a standalone python script via "Anaconda Prompt". I keep getting the error.

ImportError: No module named 'dask.dataframe';

I have installed pandas using

conda install dask

I have also installed dask via:

python -m pip install "dask[complete]"

But i still get this error. I am able to run the script in Jupyter. i have also checked i don't have a script called dask.py

Why conda for pandas but pip for dask? What happens if you import dask alone? — mdurant, Oct 29 '20 at 14:04
How are you importing dask into Jupyter? `import...` or `from import...` etc.? — gmdev, Oct 29 '20 at 14:57
worth also noting that above import statement is a must. I was trying to call `dask.dataframe.somefunction()` in code after importing dask at the top and getting this error. — horse, Apr 18 '23 at 23:26

I suspect that you are installing Dask into one environment, but running Python from another. I recommend comparing the results of ...

$ which python

or

$ which conda

and check your notebook environment by

import sys
print(sys.executable)

I suspect that they are different paths and that you are confusing two differently installed Python setups on your computer.
