Hi Dianne and all, Thank you for reporting. This is a known issue. There is a bug fix coming up concerning the HBN dataset. So this is expected. No further action needed on your side for now. You have already downloaded many datasets! An email to upgrade to a new version that has this issue resolved should appear before the workshop starts. See you soon!, Elef On Sat, Apr 22, 2023 at 1:51 PM Patterson, Dianne K - (dkp) <dkp@arizona.edu> wrote:

Dear DiPy,

I am following the instructions for DiPy 2023 and installing the tutorial data. The process seems to get quite far (3.6 GB) but then gets an error. Rerunning the command gets the same error, though nicely reports what is going on (see below)

*Environment*

Mac OS Monterey 12.6.3

*Miniconda* conda --version conda 22.11.1

conda list dipy # packages in environment at /Users/dpat/opt/miniconda3/envs/dipy: # # Name Version Build Channel dipy 1.6.0 pypi_0 pypi

python --version Python 3.10.2

*Conda Install Details*

`conda create -n dipy` `conda activate dipy` `conda install -c conda-forge dipy` `conda install -c conda-forge fury` `conda clean --all`

*Command*

dipy_fetch all

*Error (Scroll down)*

*Solutions Attempted*

I initially tried installing in the Mac's native zshell with my active conda environment. After that failed, I switched to a bash shell, just in case.

I get the same error message for both shells. In every case, I am in my dipy environment.

I tried creating a separate environment using pip instead of conda for install. That did not get far.

I have repeated the command, with equivalent results.

Thoughts?

Thank you,

Dianne
