"Bus error (core dumped)" while tree generation by fasttree

[Vivek_Thakur]

Dear community members

I recently switched over to qiime2 and getting familiarized. While running " qiime phylogeny fasttree" command, qiime aborted with error message:

**Bus error (core dumped).**

Now trying anything with qiime command flags off this message:

**Error processing line 1 of /mnt/lustre/abhishek/vth/application/miniconda2/envs/qiime2-2017.10/lib/python3.5/site-packages/matplotlib-2.1.0-py3.5-nspkg.pth:**
**Failed to import the site module**
**Traceback (most recent call last):**

**ImportError: No module named 'heapq'**

From this message it seems one of the python modules 'heapq' is missing.

Kindly let me know if this being the case.

thanks
Vivek

Hi @Vivek_Thakur! It sounds like something went wrong during installation --- can you check out the commands listed in this post to help you remove and reinstall your environment? You will need to update those commands to reference 2017.10 instead of 2017.9. Also, when you get to the step for installing QIIME 2, make sure to select the right command for your architecture (mac or linux). Keep us posted!
