Which gives me the following error:

OSError: [Errno 5] EIO
I'm sure that the camera is connected correctly (I've tested it using the standard CircuitPython code provided with it and it works) so I think that I'm misinterpreting how the readfrom_into call works... any hint?
I tried to understand what get's written in the readfrom_into part but can't get anything.. The starting code (based on circuitpython) is here: https://github.com/ArduCAM/PICO_SPI_CAM/blob/master/Python/Arducam.py
I'm trying to use a cairo.TeeSurface (pycairo version '1.21.0') to redirect input to multiple surfaces, but I cannot make it work, here is my code:
>>> import cairo
>>> s1 = cairo.ImageSurface(cairo.FORMAT_ARGB32, 500,500)
>>> s2 = cairo.ImageSurface(cairo.FORMAT_ARGB32, 500,500)
>>> s3 = cairo.ImageSurface(cairo.FORMAT_ARGB32, 500,500)
>>> s = cairo.TeeSurface(s1)
>>> s.add(s2)
>>> s.add(s3)
>>> c = cairo.Context(s)
After above iniziatilation if I try to draw a line I get an error:
>>> c.rel_line_to(100,100)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
cairo.Error: no current point defined
I tried to set explicitly a point but I get the same error:
>>> c.move_to(10,10)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
cairo.Error: no current point defined
For sure I must have misunderstood something, any clue would be appreciated.

I've trying reinstalling subprocess32, but i haven't solved anything. I'm using Python 3.6.3 Anaconda on Ubuntu 18.04.1 LTS.
Any suggestions?
I was just trying SSL-Sockets in Micropython and discovered that I can not set the connection to non-blocking as the setblocking() function is not implemented, yet.
>>> import ussl
>>> import usocket
>>> s = usocket.socket()
>>> adr = usocket.getaddrinfo('myserverwithssl.com', 443)[0][-1]
>>> s.connect(adr)
>>> s_ssl = ussl.wrap_socket(adr)
>>> s_ssl.setblocking(False)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NotImplementedError:
Looking forward to the implementation. However, is there another way to achieve nonblocking SSL-Sockets in Micropython?
Previously I have working installation of bleeding edge Theano version on Anaconda Python 2.7 x 64 on Windows 7 x64.
I tried to upgrade to bleeding edge Theano version on Python 3.5 x64 on Windows x64 and encountered error during test example compilation:

It seems libpython conflicts with Python 3.5?
