ImportError: No module named 'cfloader'

[gurkbert]

Hello,

I'm experiencing some errors when i try to update the firmware of the crazyflie 2.0. I have no problem to compile the code using 'make' but when I try to use cload i get the following error:

Code: Select all

~/Workspace/crazyflie-firmware$ make cload
../crazyflie-clients-python/bin/cfloader  flash cf2.bin stm32-fw
Traceback (most recent call last):
  File "../crazyflie-clients-python/bin/cfloader", line 2, in <module>
    from cfloader import main
ImportError: No module named 'cfloader'
Makefile:354: recipe for target 'cload' failed
make: *** [cload] Error 1

I'm using Ubuntu 16.04. Does anybody have a suggestion on how to solve this problem?

This looks like what would happen if you did not install the client with pip. Did you do it as described in the readme: https://github.com/bitcraze/crazyflie-c ... pplication?

I installed cfclient using the following command and i seemed to execute properly:

Code: Select all

~/Workspace/crazyflie-lib-python$ pip3 install -e .

The installation of the dependencies also seemed to work.

And did you install the crazyflie-clients-python as well?

[gurkbert]

I'm not sure that i understand, isn't that what

Code: Select all

pip3 install -e .

is for?

I managed to circumvent the problem by adding the paths manually:

Code: Select all

export PYTHONPATH=/home/myname/Workspace/crazyflie-clients-python/src/

Will this turn out to be problematic in any unexpected way?

If it works then it is good, though it is very strange that pip did not work. This is basically what pip should have done for you. I will run some test in a vm with a clean ubuntu to try to reproduce the problem.

I cannot reproduce the problem. On a clean Ubuntu 16.04 I did:

Code: Select all

sudo apt-get install python3-pip
git clone https://github.com/bitcraze/crazyflie-clients-python
cd crazyflie-clients-python
pip install --user -e .
sudo apt-get install python3-pyqt4 python3-pyqtgraph

cfclient # works
cfloader # works
