[Discuss-gnuradio] RuntimeError: bad lexical cast: source type value cou

Hello,

I'm trying to use 2 USRP2 using the UHD Driver.
My version is the git version of yesterday.

But when I'm trying to build a flowgraph using grc,
gnuradio isn't able to run the generated code.

The following error occurs:

RuntimeError: bad lexical cast: source type value could not be interpreted as target

And this is the generated code:

        self.uhd_multi_usrp_source_0 = uhd.multi_usrp_source(
           device_addr="addr=192.168.10.2 192.168.10.3",
           io_type=uhd.io_type_t.COMPLEX_FLOAT32,
           num_channels=2,
       )
       _clk_cfg = uhd.clock_config_t()
       _clk_cfg.ref_source = uhd.clock_config_t.REF_SMA
       _clk_cfg.pps_source = uhd.clock_config_t.PPS_SMA
       _clk_cfg.pps_polarity = uhd.clock_config_t.PPS_POS
       self.uhd_multi_usrp_source_0.set_clock_config(_clk_cfg, uhd.ALL_MBOARDS);
       self.uhd_multi_usrp_source_0.set_time_unknown_pps(uhd.time_spec_t())
       self.uhd_multi_usrp_source_0.set_samp_rate(1000000)
       self.uhd_multi_usrp_source_0.set_center_freq(2450000000, 0)
       self.uhd_multi_usrp_source_0.set_gain(20, 0)
       self.uhd_multi_usrp_source_0.set_center_freq(2450000000, 1)
       self.uhd_multi_usrp_source_0.set_gain(20, 1)

Can someone help me solving this problem?

Best regards,

Tobias
