Hi Lucas,
The point of this is to test the bug reporting system. In order to make it more useful I add small remarks regarding installation and testing I encountered so far:
1. Docker installation works fine, however, since only python3 is installed, `pip install` is not working, while `pip3 install` works
2. For testing pipe_tools matplotlib is required, however, it was not installed in Docker, adding `python3-matplotlib` to Dockerfile solved the problem
3. pipe_tools work fine as a pipe, however, they generate errors if used separately with file input/output: in surface, `np.savetxt(output.buffer, surface)` triggers `'str' object has no attribute 'buffer'` and in contact,`surface = np.loadtxt(input.buffer)` triggers the same error. Deleting `.buffer` solves the problem in both cases
Kind regards,
Andrei
