Error when importing hddm

[Selin Topel]

Dear all, 

I have been struggling with the installation and importing the hddm package on a work laptop. I am using Anaconda (also tried colab, IPython, Jupyter, Spyder), and every time, I get an error message about numpy after "import hddm" command. I tried different things like reinstalling numpy, changing the versions, reinstalling Anaconda, installing hddm in environments with python 3.7 and 3.8. Some examples of the error messages are as follows: "DLL load failed while importing _multiarray_umath: The specified module could not be found.", "numpy.core.multiarray failed to import". I also tried to define the path in the system environment but this did not change anything. The last error I got is the following:

I figured it must be something simple but I have been stuck at this step for the last three days so I would appreciate any help. 

Thank you!

Hi Selin

Was in the exact same position a week ago.
From what I gather, the installation is problematic due to non-maintained packages, which I think are being updated but will take time. 

I got things to work using docker HDDM - link. There are various threads about it in this group. 

Hope this solves it!

Best regards
