I'm sorry in advance if this has been addressed already, I haven't found any information in previous posts that has worked.
Everything that I see so far points to a permission or path issue but I am stuck at this juncture. I'm posting the error message(s) that occurs when I try to launch the client:

INFO:cfclient.gui:Disabling STL printouts
Traceback (most recent call last):

When I run the script, I'm in the ~/crazyflie-clients-python/bin directory and I run as $python3 cfclient
Hopefully someone can help point me in the right direction. Thank you in advance for your time!

Hi,

How did you install the client? Did you follow these instructions: https://github.com/bitcraze/crazyflie-c ... hon/#linux ?

From the message it looks like pyqt5 is not installed so you are likely missing the apt-get part of the instruction.

Hello Arnaud,
thank you for your response. I have tried the command sequence numerous times with the same results.

Let me ask a simple question, which directory should I be in when I execute the following commands:
$sudo apt-get install python3 python3-pip python3-pyqt5
$pip3 install -e .

Should the directory be:
Home
/crazyflie-clients-python
or
/crazyflie-clients-python/bin ?

Thanks again for your assistance.
Regards,
Season

"sudo apt-get install python3 python3-pip python3-pyqt5" can be executed anywhere.

"pip3 install -e ." has to be executed in the crazyflie-clients-python folder cloned from git.

What output do you have in the console when you type the commands?

Sorry about the delay Arnaud,
After reading more I was concerned about the Python version. Everything references v3.5 but I had been running v3.6
I reinstalled Python to have v3.5 (on Ubuntu 16.04) and started again from scratch. The permission errors seemed to have disappear but a new problem is shown.

When I execute cfclient from the ~/crazyflie-clients-python/bin directory I receive a core dump error:

INFO:cfclient.gui:Disabling STL printouts
Segmentation fault (core dumped)

I haven't been able to get past this error but am looking at archived information.
Thanks,
Season

Python 3.6 will work, I have been running both 3.5 and 5.6 without any problems.

Could you please describe the procedure you are following to install the dependencies and the client? This error could have a number of reason and it is hard to guess without knowing what you have installed.
