Problem running the program #35

Closed hkazmi25 closed 3 years ago

hkazmi25 commented 3 years ago

File "h5py\h5.pyx", line 1, in init h5py.h5 ImportError: DLL load failed: The specified procedure could not be found.

I created a new environment of abtem, I installed by using pip install abtem.. I install h5py as well. i can see everything is perfectly install in my computer when i find the conda list abtem .. but still i am getting this error.

Which versions of hdf5 and h5py are you using? Overall, the problem seems to be that your conda environment is not finding the DLL file; this is Windows-specific problem that seems to be relatively common.

I have seen this error before. You can search for "python hdf5 DLL load failed".

I believe this will work to create a functional abTEM env on windows:

conda create -n abtem python=3.8
conda activate abtem
conda install anaconda
pip install abtem

Let us know if it does not work.

This is a useful issue as I believe many windows users will face the same problem. So I should create a common issues section in the install instructions.

hkazmi25 commented 3 years ago

So i tried almost everything i know to my limited knowledge. It doesn't work in windows. install, reinstalled from scratch. the error now i am struggling with is \h5py> python .\setup.py build..

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

I did install C++ 14.0 ... and greater as well, restarted my many time computer but still the problem continues. I know windows sucks. :(

Your issue seems to be with hdf5 for python, which is a very common package in electron microscopy and works on windows.

To see if this really does not work you could create a new env and install h5py

>>> conda create -n h5py_test python=3.8
>>> conda activate h5py_test
>>> conda install h5py

Open python and test it:

>>> python
>>> import h5py

Let me know if this works.

@hkazmi25 could you please give us feedback on whether this instruction helped you?

I am closing this. Please reopen if you still have this issue.
